I lost a phone on the Columbia River in 2023. One moment of inattentiveness, a hard turn into chop, and my $900 iPhone was at the bottom of a river. Since that weekend I have been on a personal mission to figure out which jet ski dry bags actually keep gear dry when the water gets rough. I have ridden with eight different bags since then, from budget roll-tops to submersible PWC-specific pouches, and the difference between a dry bag and a dry-feeling-but-actually-wet bag is enormous.
A jet ski dry bag is a waterproof storage container built for personal watercraft. Most use roll-top closures or sealed zippers, paired with welded seams, to keep spray, splash, and brief submersion out of your gear. On a PWC you are constantly getting hit by water from every direction, so a regular backpack or soft cooler simply will not cut it. Whether you ride a Sea-Doo, a Yamaha WaveRunner, or a Kawasaki Jet Ski, a proper dry bag protects your phone, keys, wallet, spare clothes, and any electronics you bring along for the ride.
This guide covers the eight best jet ski dry bags I have personally used or researched in depth for 2026, from compact phone pouches to 45L touring duffels. I tested each one for waterproofing, comfort, mounting options, and durability in real PWC conditions. If you have ever had to ride with a ziplock bag holding your phone, or you are planning your first multi-day jet ski tour, you will find something here that fits your needs and your budget.

1. MARCHWAY Floating Dry Bag Backpack – Best Overall
MARCHWAY Floating Waterproof Dry Bag Backpack 5L/10L/20L/30L/40L, Roll Top Sack Keeps Gear Dry for Kayaking, Rafting, Boating, Swimming, Camping, Hiking, Beach, Fishing (Dark Blue, 5L)
500D tarpaulin
Welded seams
Floats when sealed
5L-40L sizes
Pros
- Excellent waterproofing when properly sealed
- Multiple size options from 5L to 40L
- Versatile carrying with shoulder strap or backpack straps
- Durable welded seam construction
- Floats when sealed correctly
Cons
- Requires 3-4 folds for effective waterproofing
- Not designed for extended submersion
I bought the MARCHWAY 20L version three years ago and it has been on every jet ski trip since. The first thing I noticed was how light it felt at only 8.8 ounces. That mattered when I was already carrying a life vest, a tow rope, and a waterproof phone case. The bag barely registered on my shoulders even on a four-hour ride along the Oregon coast.
The waterproofing is excellent as long as you roll the top correctly. I made the mistake of only doing two folds on my first ride and ended up with a damp sandwich wrapper inside. After reading other riders’ tips on the r/jetski subreddit, I started doing three full rolls and buckling the top strap, and the bag has not leaked a single time in dozens of trips since. That extra fold takes about five seconds and makes the difference between a dry phone and a brick.
The welded seams are a big upgrade over cheaper sewn-seam bags I had used before. After two summers of being tossed around in the back of my WaveRunner and dragged across gravel parking lots, there is not a single seam failure or pinhole. Reviewers on Amazon confirm this pattern, with the bag holding a 4.7-star rating across 34,102 reviews, which is unusual for a budget-priced item. The high-visibility colors also help when you drop the bag overboard and need to spot it bobbing on the surface.
I also like that it doubles as a backpack on the 20L and larger sizes. I can hike it from the launch ramp back to my truck without switching bags. The D-ring on the side is handy for clipping it to a tow point on the ski. Overall, this is the bag I grab first when I head out, and it is what I recommend to any friend who asks for a single jet ski dry bag recommendation.
For whom it is good
This bag is perfect for riders who want one versatile dry bag that works for jet skiing, kayaking, rafting, and beach trips. The 20L size fits a change of clothes, towel, snacks, and a phone case comfortably. It is also a great pick for families because the smaller 5L and 10L sizes work for kids who just need to keep their phone and a snack dry.
For whom it is not great
If you need a true submersible bag that can survive going overboard in choppy water with a full electronics load, look at the IP68-certified options below. The MARCHWAY is water-resistant under splashes and brief dunkings but is not rated for sustained submersion. Also, if you need quick-access pockets for keys or a wallet, this simple roll-top design will not give you that.
2. Earth Pak Waterproof Dry Bag – Best with Phone Case
Earth Pak 10L Waterproof Dry Bag – Marine Roll Top Dry Sack for Kayaking
500D PVC
IPX8 phone case
5-year warranty
55L max
Pros
- Named top dry bag by NY Times Wirecutter 2024
- Includes IPX8 waterproof phone case
- 5-year warranty for peace of mind
- Excellent seal and waterproof performance
- Comfortable backpack straps on larger sizes
Cons
- Initial plastic smell that can be removed with vinegar rinse
- Shoulder straps can be a weak point on smaller sizes
- Phone case lanyard can be fragile
The Earth Pak has a near-cult following in the kayaking world, and I can see why after using the 55L version on a five-day PWC camping trip on Lake Powell. The 500D PVC material feels noticeably more substantial than cheaper bags, and the welded seams give it that satisfying solid feel when you squeeze it. The roll-top closure works exactly the same way as the MARCHWAY but feels a little more refined in how the folds lay flat.
The killer feature is the included IPX8 waterproof phone case. Most dry bag makers sell these cases separately for around $15, so getting one in the box is a real value. The case fits my iPhone 15 Pro Max with a slim case on it, and I have used it to take underwater photos at the lake without any leakage. On jet ski rides, I slide the phone into the pouch on the front strap so I can glance at GPS without opening the dry bag. That alone is worth the price of admission.
Earth Pak backs this bag with a 5-year warranty, which is unusual at this price point. I have read reviews from buyers who had a strap fail after two years and got a free replacement without hassle. That kind of warranty support matters on a product you are trusting to keep electronics dry. The bag itself is rated by Wirecutter as a top dry bag for 2024, and reviewers consistently mention the quality of construction.
On the downside, the bag has a strong plastic smell when you first open it. I rinsed it with a 50/50 mix of water and white vinegar before the first trip, and that took care of it. The shoulder straps on smaller sizes (10L, 20L) are thinner than I would like, but the backpack straps on the 30L and 55L versions are padded and comfortable for long carries.
For whom it is good
Riders who want a bag-and-phone-case bundle in one purchase. The 55L size is ideal for multi-day jet ski camping trips where you need to carry clothes, food, and electronics. Anyone who values warranty support will appreciate the 5-year coverage. It is also a strong pick for riders who like to take underwater photos while on the water.
For whom it is not great
The smell out of the box is a dealbreaker for some riders who want a grab-and-go experience. If you are sensitive to PVC off-gassing, plan to air the bag out for a day or rinse it before use. The larger sizes also get heavy when fully loaded, so solo riders who want to keep things minimal might prefer a smaller option.
3. HEETA Dry Bag Waterproof Backpack – Best Transparent Design
HEETA Dry Bag Waterproof Backpack with Phone Case (Transparent Black, 20L)
Transparent PVC
Free phone case
11 colors
5L-40L sizes
Pros
- Transparent design makes finding items easy
- 11 color choices including high-visibility options
- Solid waterproof performance in real conditions
- Includes free waterproof touch-screen phone case
- Lightweight and comfortable to carry
Cons
- 20L backpack straps can dig into bare shoulders
- Not designed for extended submersion
- Some quality control issues with stitching reported
The HEETA dry bag is the only fully transparent option on this list, and that turns out to be more useful than I expected. On a jet ski, you are usually moving too fast to dig through a bag looking for a specific item. Being able to see through the side and instantly spot your sunscreen, wallet, or car keys saves real time when you are anchored in a cove and need to grab something quickly.
I tested the 20L version in the Pacific chop near Catalina, and the bag held up well over a full day of riding. The PVC is slightly thinner than the Earth Pak at 0.3mm on the sides (with 0.6mm on the bottom for reinforcement), but it is still strong enough that I did not worry about tears. The welded seams look cleaner than stitched bags at this price, and the roll-top closure worked exactly as expected after three folds and a buckle.
HEETA includes a free waterproof phone case with the bag, similar to Earth Pak. The case is a touch-screen-compatible model that lets you use your phone without removing it from the pouch. The 11 color choices are a nice touch for riders who care about matching their gear, and the high-visibility yellow and orange options help with safety on the water.
My main gripe is that the 20L backpack straps are narrow and tend to dig into bare shoulders during long carries. The 30L and 40L versions have wider, padded straps, so if you plan to hike with the bag often, go up a size. Some reviewers mention stitching issues at the buckle attachment points, so inspect that area when you receive the bag.
For whom it is good
Riders who value quick visual access to their gear and want to skip the digging. The transparent design also makes this a fun choice for families with kids who want to see their toys and snacks inside. The 11 colors make it easy to match personal watercraft accessories or stand out for safety.
For whom it is not great
The transparent material shows every smudge and water spot, so if you want a bag that looks clean, plan to wipe it down regularly. Riders who carry a lot of weight on long hikes should size up to the 30L or 40L version for better strap comfort. If you need truly submersible protection, you will need a different bag.
4. Pelican Marine IP68 Dry Bag – Best IP68 Certified
Pelican Marine IP68 Waterproof Dry Bag 2L w/Phone Pouch/Case – Black/Yellow
IP68 waterproof
Built-in 7-inch phone pouch
POM buckles
2L
Pros
- IP68 certified waterproof protection that exceeds most bags
- Built-in touchscreen phone pouch works through the clear window
- Floats in water when properly sealed
- POM buckles and D-rings for durability
- Compact size for essentials
Cons
- Roll-top seal requires practice to close correctly
- Some issues with strap quality reported
- Phone pouch zip-lock can be tricky to seal
- 2L capacity limits what you can carry
Pelican is a brand you trust when you need serious protection, and the IP68 rating on this dry bag is one of the few legitimate certifications in this category. IP68 means the bag is rated for continuous submersion beyond 1 meter, which is more than most jet ski riders will ever throw at it. After testing this bag in actual submersion tests in a pool, it kept my wallet, phone, and keys bone dry for 30 minutes at chest depth.
The built-in touchscreen phone pouch is the standout feature. Unlike a separate phone case that dangles or straps to the bag, this one is built into the front of the bag with a clear window that works with touchscreens. I could check my GPS map, scroll through music, and even answer a call without taking the phone out. The pouch fits phones up to 7 inches, which covers every modern flagship including the iPhone Pro Max and Samsung Galaxy Ultra.
The POM buckles and D-rings are tougher than the plastic hardware on cheaper bags. POM (polyoxymethylene) is the same material used in high-end ski bindings and tactical gear, so it should hold up to saltwater exposure much better than standard nylon buckles. Reviewers on the Seadoo Forum Facebook group specifically mention the Pelican hardware outlasting other bags they had tried.
The downsides are real, though. The roll-top seal needs more practice than other bags to close correctly, and the phone pouch zip-lock is stiff out of the box. With only 2L of capacity, this is an essentials-only bag, not a touring bag. For jet ski riders who just need to protect their phone, keys, and a wallet on day rides, it is excellent.
For whom it is good
Riders who want the highest waterproof certification available and who only need to carry essentials on day rides. The built-in phone pouch is perfect for navigation use during rides. Saltwater riders will appreciate the corrosion-resistant POM hardware that holds up better than plastic buckles.
For whom it is not great
If you need to bring a change of clothes, food, or anything beyond small essentials, the 2L size will not work. Riders who want a grab-and-go bag with no learning curve should look at the MARCHWAY or HEETA instead. The higher price also makes this a tougher sell for budget-conscious riders.
5. Pelican ExoDry 10L Drybag – Best Compact for Essentials
Pelican ExoDry 10L Small Drybag – Waterproof – Shoulder Strap – Thick & Lightweight – Roll Top Dry Compression – Keeps Gear Dry for Kayaking, Beach, Rafting and Fishing – Black
500D PVC
Removable shoulder strap
Reflective logo
10L-30L
Pros
- Thick durable 500D PVC material
- Excellent waterproof performance
- Comfortable removable shoulder strap
- Reflective logo for low-light visibility
- Front pocket for quick-access items
- Floats when sealed
Cons
- Some reports of seams shedding over time
- Strap adjustment can slip without locking
- No handle strap on top for easy grab
- Limited size options
The Pelican ExoDry sits in a sweet spot between the larger touring bags and the ultra-compact IP68 pouch. At 10L, it fits a phone, wallet, keys, a small towel, and a snack, which is exactly what I bring on most half-day rides. The 500D PVC feels tank-like compared to budget bags, and I appreciated the reflective logo on my last evening ride when I dropped the bag in the parking lot and could find it with my phone flashlight.
I tested the 10L version on Lake Havasu for a full Saturday of riding, and the waterproof performance was perfect. The roll-top closure takes three folds to seal correctly, and the bag never let in a drop of water even when I took a hard wave over the bow that drenched everything else on the ski. The removable shoulder strap is comfortable, and I like that I can take it off if I am storing the bag in a tight compartment on the PWC.
The front pocket is a small but useful feature. It is not waterproof itself, but it is great for storing a GoPro mount, a small multitool, or a carabiner that you want to grab without opening the main compartment. The integrated loops on the bottom let you clip the bag to tie-down points with a carabiner, which is how I secure it to the rear grab handle of my WaveRunner.
The most common complaint in reviews is that the strap adjuster can slip under heavy load. I solved this by tying a small overhand knot in the strap webbing after adjusting it, which locks it in place. A few long-term reviewers also mention seam shedding after a season of heavy use, so inspect the seams every few months.
For whom it is good
Riders who want a compact, no-nonsense bag for essentials on day rides. The 10L size is ideal for shorter riders who do not want a huge backpack between their shoulders. The reflective logo and carabiner loops make this a strong choice for evening rides and riders who anchor in remote spots.
For whom it is not great
If you need to carry a change of clothes or pack for overnight trips, the 10L is too small. Riders who hate fiddling with strap adjusters might find the slipping strap annoying. For larger capacities in the same brand, Pelican offers 20L and 30L versions of the ExoDry at higher prices.
6. CALPALMY 20L Jet Ski Anchor Kit – Best 2-in-1 Anchor and Dry Bag
CALPALMY 20L Jet Ski Anchor Kit, 2-in-1 Sand Anchor Bag with Buoy
Sand anchor plus dry bag
50 lb capacity
12 ft rope
Marine-grade PVC
Pros
- 2-in-1 sand anchor and dry bag functionality
- Holds up to 50 lbs of sand for solid anchoring
- Heavy-duty marine-grade PVC with welded seams
- Quick fill and easy empty design
- High-visibility floating design
- Includes 12 ft braided anchor rope and stainless steel clips
Cons
- Handle may rip when lifting heavy filled bags
- Not fully submersible as a dry bag
- Limited dry storage capacity once anchor role is the main use
The CALPALMY 20L is one of the most clever products I have come across for jet ski riders. It pulls double duty as both a sand anchor and a dry bag, which solves a real problem for PWC owners who anchor in calm bays to swim, fish, or relax. I tested this on Lake Mead, filling it with about 35 lbs of sand from the shore, and it held my WaveRunner steady in moderate wind and current. The 12 ft braided rope gives you good swing radius without drifting into other boats.
As a dry bag, it works fine for storing your wallet, phone, keys, and a small towel while you are anchored. The marine-grade PVC and welded seams give it a solid feel, and the high-visibility yellow color is easy to spot on the water. The stainless steel clips resist corrosion in saltwater better than standard steel hardware, which matters if you ride in the ocean.
The biggest limitation is that this is not a true submersible dry bag. It is water-resistant and keeps splashes out, but it is not designed to keep gear dry if fully submerged. If you need a bag specifically for electronics protection, look at the IP-rated Pelican options instead. As an anchor, however, this product is excellent and beats dragging a dedicated mushroom anchor onto your ski.
The most reported issue is the handle ripping when the bag is fully loaded with sand and lifted by one person. I always lift from the bottom corners or use the rope to pull it up rather than trusting the single handle. With 881 reviews averaging 4.2 stars, most users have a positive experience with proper loading technique.
For whom it is good
Riders who anchor frequently in calm bays and want to consolidate gear. If you do not want to buy a separate anchor and dry bag, this 2-in-1 design saves money and storage space. The included rope and clips mean you have everything you need right out of the box.
For whom it is not great
If you need a true waterproof bag for electronics, this is not the right pick. Riders who anchor in deep water with strong current will want a heavier dedicated anchor. The limited capacity also means this is not a touring bag, so you will still need a separate solution for multi-day trips.
7. KEMIMOTO 45L Waterproof Duffle – Best Large Capacity
KEMIMOTO Waterproof Duffle Bag 45L Heavy Duty Marine Dry Bags Backpack Jet Ski Motorcycle Tail Bag Large Storage Travel Luggage For Boat Camping With Quick-Fixed Straps
6-level sealed zipper
PE reinforced frame
600D fabric
45L
Pros
- Truly waterproof with 6-level sealed zippers
- 45L capacity fits life jacket
- outfits
- towels
- and gear
- PE reinforced frame resists impact and deformation
- 600D fabric resists seawater
- UV rays
- and weather
- Ergonomic padded handles with quick-release buckle mounting
- Air valve for compact storage
Cons
- Zipper can be tight and difficult to operate at first
- No internal structure keeps shape when empty
- Not intended for full submersion
The KEMIMOTO 45L is the bag I bring on every multi-day jet ski trip. With 45 liters of capacity, it swallows a change of clothes, a towel, a camp shirt, food, a first aid kit, and still has room for extras. The PE reinforced frame is the standout feature. Unlike soft dry bags that slump over when not full, this duffel holds its shape even when empty, which makes it much easier to load in the back of a PWC where space is tight.
The 6-level sealed zipper is a different approach than roll-top bags, and it took me a few tries to get used to. Once you seat the zipper and press down the protective flap, it creates a genuinely waterproof seal. I tested it under a running hose and in a brief dunking, and the contents stayed dry. The zipper is stiff out of the box but loosens up after a few uses.
The quick-release buckle mounting system is exactly what jet ski riders need. Most dry bags just have a D-ring, which is fine for kayaks but awkward on a PWC. The KEMIMOTO has actual mounting straps with quick-release buckles that click onto most PWC tie-down points or rear grab handles. I secured mine across the rear seat of my Sea-Doo GTX in under a minute.
The 600D fabric is rated for seawater and UV exposure, which is important for ocean riders who leave their gear on the ski between trips. The air valve lets you compress soft contents like sleeping bags and clothes for more efficient packing. At a 4.5-star rating across 19 reviews, this is a newer product, but the early feedback is overwhelmingly positive.
For whom it is good
Riders who take multi-day jet ski camping trips or carry a lot of gear on day rides. The quick-release mounting makes this far easier to attach to a PWC than traditional duffels with just a D-ring. Ocean riders will appreciate the UV and saltwater resistance of the 600D fabric.
For whom it is not great
If you only need a small essentials bag for quick rides, the 45L size is overkill. The stiff zipper is a learning curve, and riders who hate fiddling with hardware should look at simpler roll-top designs. Newer product with limited long-term reviews means long-term durability is still being established.
8. Jettribe Waterproof PWC Ride Bag – Best PWC-Specific Design
Jettribe Waterproof PWC Ride Bag – Submersible Dry Bag Pouch with Triple Snap-Lock & Heat Welded Seams – Adjustable Shoulder Strap Crossbody for Jet Ski, Kayaking, Boating & Beach – 11″ x 8.5″
Triple snap-lock
Heat-welded seams
Clear window
11x8.5 inch
Pros
- 100% submersible protection with triple snap-tight locks
- Heat-welded waterproof seams for true submersion
- Clear view front window for phone or small tablet
- Heavy-duty marine construction with puncture-resistant materials
- Secure adjustable shoulder strap with detachable snap hooks
- Dimensions designed specifically for PWC storage compartments
Cons
- New product with no customer reviews yet to verify long-term performance
Jettribe is a brand that focuses exclusively on jet ski and PWC gear, and you can feel that specialization in this dry bag. The 11-inch by 8.5-inch footprint is specifically designed to fit in the storage compartments of popular PWCs including Sea-Doo, Yamaha, and Kawasaki models. After sliding it into the front storage of my Sea-Doo GTI, it fit perfectly with no wasted space.
The triple snap-lock closure is a different approach than the typical roll-top or zipper. It uses three heavy-duty plastic snaps along the top fold, creating a mechanical seal that does not depend on user technique to get right. I tested this in the pool and got my phone and wallet back completely dry after 10 minutes of full submersion. The heat-welded seams are the same construction used on inflatable boats and commercial marine gear.
The clear front window is a nice touch that lets you check your phone or use it as a basic camera viewfinder without opening the bag. The detachable shoulder strap with snap hooks lets you clip the bag to a tow point or your life vest D-ring for hands-free carrying. The PWC-specific dimensions and submersible rating make this a strong pick for riders who prioritize jet ski-focused design.
The honest caveat here is that this is a new product with no customer reviews yet on Amazon. The spec sheet looks solid, but I have not had time to test long-term durability across multiple trips. The brand itself has a good reputation in the PWC community, which gives me more confidence than I would have with an unknown brand.
For whom it is good
Riders who want a bag specifically sized for PWC storage compartments. The triple snap-lock is great for anyone who has struggled to get a roll-top seal right every time. The submersible rating makes this a strong pick for riders who frequently end up in the water with their gear.
For whom it is not great
If you prefer the reassurance of thousands of customer reviews, wait until this product accumulates more feedback. The small size limits what you can carry, so this is not a touring bag. If you ride larger PWCs without specific storage compartments, a different bag might fit your setup better.
How to Choose the Right Jet Ski Dry Bag?
Picking the right jet ski dry bag comes down to matching the bag to your riding style, the gear you carry, and how you mount it to your PWC. Here are the key factors I consider when helping friends choose between these options.
Size and Capacity Guide
Most jet ski riders do well with a 20L to 30L bag for day trips. That is enough space for a phone, wallet, keys, a change of underclothes, a small towel, and snacks. For multi-day tours where you need real clothing and camping gear, bump up to 40L or 45L. For pure essentials-only rides where you just want your phone and keys protected, a 2L to 10L bag is the right call.
I made the mistake early in my riding career of buying a 55L bag thinking bigger was better. The extra space just meant I packed more weight, which made the bag awkward to mount and harder to retrieve gear from while riding. Match your bag to your actual gear list, not your imagined maximum.
Closure Type: Roll-Top vs Zipper vs Snap
Roll-top closures are the most common on jet ski dry bags and the most reliable when sealed correctly. The key is three to four full rolls before buckling the strap. Reviewers on the r/jetski subreddit consistently mention that the difference between a leaking and non-leaking roll-top bag is the number of folds. Fewer folds mean more water intrusion risk.
Sealed zippers are easier to use day-to-day but require careful sealing. The KEMIMOTO 6-level zipper is the best I have tested, but it still took me a few tries to get it right. Snap-lock closures, like the Jettribe bag, are the easiest to use correctly every time, but they limit the bag shapes you can get.
If you are deciding on a bag type for the first time, a roll-top is the safest pick because parts are easy to replace. Replacement sealed zippers are harder to find, and snap locks are usually proprietary to each brand.
Material Matters: PVC vs TPU-Coated Nylon
Most jet ski dry bags use 500D PVC (polyvinyl chloride) as the main material. It is durable, waterproof, and inexpensive. The downsides are that PVC is heavier than alternatives and can have a strong smell out of the box. TPU-coated nylon is lighter and more flexible but typically more expensive.
For saltwater riding, look for UV-resistant fabric like the KEMIMOTO 600D material. Standard PVC breaks down faster under prolonged sun exposure, and saltwater accelerates that process. Rinse any bag with fresh water after ocean rides to extend its life significantly.
LinQ System Compatibility for Sea-Doo Owners
If you ride a newer Sea-Doo with the LinQ quick-release mounting system, you have a specific advantage. LinQ lets you click accessories onto your ski in seconds without tools. While most dry bags on this list are not LinQ-native, you can adapt them by attaching LinQ-compatible base plates to the bottom of any bag with a flat surface.
The KEMIMOTO 45L with its quick-release buckle system is the closest to LinQ convenience on this list. For a true LinQ dry bag solution, Jet Tech makes a 195L touring bag that mounts directly to LinQ attachment points. That is overkill for most day riders but perfect for extended Sea-Doo touring.
Mounting Tips for Personal Watercraft
Mounting a dry bag to a PWC is one of the most common pain points riders mention in forums. Generic waterproof boxes mounted to the hood leak because the hood is not designed for that load, and water pools in unexpected ways. The better approach is to mount to grab handles, tow points, or dedicated cargo nets behind the seat.
I use a small cargo net behind the rear seat of my WaveRunner to secure most dry bags. For larger bags like the KEMIMOTO 45L, I use the included quick-release straps clipped to the rear grab handles. Always check that your bag is secure before riding, because a loose bag can become a projectile in a hard turn or a wave impact.
If you are shopping for jet pumps or other PWC maintenance gear alongside a new dry bag, plan the storage layout of your ski before buying. A bag that fits perfectly in your storage compartment is worth more than one with slightly better specs that does not fit.
Frequently Asked Questions
What is the best waterproof dry bag for a jet ski?
The MARCHWAY Floating Dry Bag is our top pick for most jet ski riders. It uses 500D tarpaulin with welded seams, has a roll-top closure that seals when rolled three to four times, and floats when properly sealed. With over 34,000 reviews averaging 4.7 stars, it is also the most battle-tested option in this category.
Can dry bags be submerged in water?
Some dry bags can be submerged, but most cannot. Standard roll-top and zipper dry bags are designed to handle splashes and brief dunkings, not sustained submersion. For true submersible protection, look for IP67 or IP68 ratings, like the Pelican Marine IP68 bag, which is rated for continuous submersion beyond 1 meter of depth.
What size dry bag do I need for jet skiing?
For day trips, a 20L to 30L bag holds a phone, wallet, keys, a small towel, and snacks comfortably. For multi-day tours with camping gear and clothing, step up to 40L or 45L. For essentials-only rides where you just protect your phone and keys, a 2L to 10L bag works well and is easier to mount.
Are Heeta dry bags good for jet skiing?
Yes, HEETA dry bags work well for jet skiing. The transparent PVC design is useful for spotting items quickly, the roll-top closure seals effectively after three folds, and a free waterproof phone case is included. The 20L version has over 36,000 reviews averaging 4.6 stars, making it one of the most popular options in the category.
How do I attach a dry bag to my jet ski?
Mount the bag to rear grab handles, tow points, or a cargo net behind the seat. Avoid mounting to hood latches or non-reinforced plastic surfaces because water pools there and leaks are common. The KEMIMOTO 45L has quick-release buckle straps that clip to most tie-down points in under a minute, while smaller bags can be secured with carabiners through the D-rings.
Final Verdict on the Best Jet Ski Dry Bags
After testing these eight jet ski dry bags across multiple PWC models and riding conditions, the MARCHWAY Floating Dry Bag is still the best overall pick for most riders in 2026. It hits the sweet spot of waterproof performance, durability, size options, and price. The Earth Pak is the runner-up if you want a bundled phone case and longer warranty, and the Pelican Marine IP68 is the right choice if you need true submersible protection.
For larger capacity multi-day trips, the KEMIMOTO 45L is hard to beat, and the CALPALMY anchor kit is the most useful 2-in-1 product I have found for riders who anchor frequently. Match the bag to your actual riding style rather than chasing the highest specs, and you will end up with the best jet ski dry bag for your needs. If you are also shopping for waterproof vinyl flooring for your garage or shop, the same waterproof principles apply across marine and home gear.
