You buy a dry bag so your phone, keys, and clothes stay dry through a kayak trip, a raft ride, or a downpour. Match the bag’s capacity to your trip: a 3-liter case suits a day on the water, while a 60-liter duffel fits a camping trip. Pick the size, closure, and material that fit how you will actually use it.

Whether you paddle, camp, or just commute in the rain, these are the best-reviewed dry bag options that keep your valuables safe on every water adventure.
Our Picks at a Glance
How To Choose The Best Dry Bag
A dry bag’s sole job is to keep water out, regardless of brand. Choose based on capacity, carry style, and expected water exposure.
Capacity: Match the Liters to Your Load
Small bags in the 3L to 10L range are for essentials — a phone, wallet, keys, and maybe a snack. Mid-size 20L to 30L bags handle a towel, a change of clothes, and shoes for a day at the beach. If you are packing for a multi-day trip or carrying gear for two people, you are looking at 60L and up. A 3-liter case holds a fraction of what a 20-liter roll-top holds — that is a 6.7x gap in capacity — so think carefully about what “dry” means for your trip.
Closure: Roll-Top vs. Magnetic vs. Zipper
The roll-top seal—fold the top three to five times and clip—is the most reliable for keeping water out. Magnetic closures offer quick access but depend on strong magnets for a watertight seal. Zippers are convenient but the least waterproof closure option. For submersion, a tightly folded roll-top outperforms other closures.
Material and Seams Matter More Than You Think
Most dry bags are made of PVC, nylon, or tarpaulin. Welded or tape-sealed seams prevent leaks better than stitched ones. A polyurethane-coated nylon bag like those from Sea to Summit is lighter and packs smaller, while a heavy-duty PVC bag like Earth Pak stands up to rock scrapes better.

In‑Depth Reviews
1. YETI Sidekick Dry 3L Gear Case, Olive
Our pick — over 4.5★ from 900+ verified ratings; the strongest balance of quality and price.
The premium sidekick that clips onto your YETI tote and shrugs off river spray.
This is the dry bag for people who already own a YETI Camino or Hopper and want a matching, perfectly integrated accessory. It uses a HydroShield closure with powerful magnets to create a 100% waterproof shield, and the RF-welded seams leave no weak stitching for moisture to sneak through. The shell is made of the same kind of durable materials used in high-performance whitewater rafts, so it is built to take a beating.
At 3 liters it is not a duffel — it is a catch-all for your wallet, phone, and earbuds, with room to spare. The outside measures just 11.75 x 7.13 x 3.25 inches, which keeps it compact enough to tuck into a tote without adding bulk. Buyers report it holds up beautifully after months of use, including multiple rides on boats, and that the magnetic closure seals tight enough to keep electronics perfectly dry.
The thing everyone raves about is the build quality — thick, easy-to-clean material that feels far more substantial than its size suggests. It is equally at home on a beach trip as it is clipped to a cooler for a river float. The only real follow-up question is why you would buy it if you do not own a YETI tote, since that is where it shines brightest.
Premium feel: The magnetic closure and welded seams deliver a waterproof seal that buyers trust with phones and wallets, praising the quality above all else.
Right fit: It shines as an add-on to YETI totes and coolers, but a separate strap is not included, so plan to clip it or buy one.
Reach for this if: you want a tough, compact case that clips onto your YETI gear and keeps essentials dry on the water.
Look elsewhere if: you need to carry towels, shoes, or a change of clothes — 3 liters is essentials-only territory.
2. MARCHWAY Floating Waterproof Dry Bag Backpack
The budget-friendly floater that kayakers buy again and again in different colors.
If you want a dry bag that does the job without emptying your wallet, this is the crowd favorite. The roll-top closure creates a watertight seal — you spread the round bottom open, roll the top down 3 to 5 times, and buckle it shut. The trapped air blocks water and gives the bag buoyancy, so it floats visibly on the surface if it goes overboard, making your gear easy to spot and retrieve.
It comes in a huge range of sizes, from 5L to 40L, so you can match the bag to the trip. The 20L version reviewed here is a versatile middle ground, and it uses backpack straps for even weight distribution on heavier loads. The reinforced multi-layer tarpaulin construction is designed to handle rock scrapes and harsh conditions, with welded seams, heavy-duty buckles, and sturdy straps backing it up.
The quality is so good that owners mention buying three or four more after the first one. The round bottom helps you capture air quickly for that float, and the reinforced D-ring lets you fasten it to your kayak so it stays within reach.
Why owners stick with it
- Floats visibly when sealed, so dropped gear is easy to find
- Roll-top seal keeps contents dry in rapids, waves, and snow
- Every size folds into its own compact pouch for storage
What to keep in mind
- Designed for floating, not extended submersion underwater
- Smaller 5L/10L sizes lack backpack straps
Best for: kayakers, rafters, and beachgoers who want a reliable, floating dry bag at a budget-friendly price.
Think twice if: you plan to fully submerge the bag for long periods — this one is built to float, not dive.
3. HEETA Waterproof Dry Bag Backpack with Zippered Pocket
The dry bag with a quick-access front pocket that saves you from unrolling the top.
The standout feature here is the splash-proof zippered pocket on the front. You can reach your keys, cash, or ID without unrolling the top and rummaging through your whole bag — a small convenience that makes a big difference on a paddleboard. The main compartment uses a solid roll-top closure system that keeps items dry as long as the bag is not fully submerged.
The material is an upgraded 0.02in (0.5mm) triple-layer PVC: a durable inner layer, a patch mesh middle layer, and a reinforcement coating outside. That makes it wear-resistant and scratch-resistant across all kinds of weather. It comes in five sizes from 5L to 40L and six colors, with the smaller sizes getting a shoulder strap for cross-body carry and the larger ones getting backpack straps.
Buyers love that it floats if dropped in the water accidentally, and one snorkeler kept their electronics dry for over two hours in the ocean. The 10L size fits a towel and shoes comfortably, though the front pocket is too small for a large phone — treat it as a keys-and-cards pocket instead.
Quick-access win: The front zippered pocket is what sets this apart, letting you grab small essentials without breaking the waterproof seal.
Honest note: The front pocket is splash-proof, not fully waterproof, and too small for most phones.
Reach for this if: you paddle or snorkel and want a floating bag with a convenient pocket for small items.
Look elsewhere if: you need your phone in an easily accessible, fully waterproof front pocket.
4. Osprey Ultralight Waterproof Dry Sack
A featherweight organizer for dayhikes that clips right onto your pack.
This is more of an organizational tool than a standalone adventure bag. The rectangular shape packs efficiently into a daypack, and the waterproof-coated fabric and seams keep moisture out. It meets IPX5 standards, which means it is waterproof against splashing but not designed for submersion. At just 0.07lb, it adds almost no weight to your load.
The D-ring makes it easy to clip onto a backpack or hang it out to dry. Buyers use it to roll up a neck pillow for travel, stuff a fleece jacket into it for hiking, or keep wet clothes from transferring moisture to the rest of their gear after the beach. One hiker used it as a compression sack for a puffer jacket, gloves, and scarf on a trip.
The 6-liter capacity is perfect for essentials like a phone, sunglasses, sunblock, and a shirt on day trips. The thin material dries quickly, and the roll-top closure keeps things simple once you figure out the fold.
Packable helper: The lightweight build and D-ring make it a natural add-on to any backpack for organizing layers or wet clothes.
Keep it honest: This is a splash-and-rain guard, not a submersion bag — treat it accordingly.
Best for: dayhikers and travelers who want a light, packable way to organize gear and isolate wet clothes.
Think twice if: you need a bag that can survive being fully dunked in a river or lake.
5. Earth Pak Waterproof Dry Bag with Phone Case
The kayaking heavyweight that throws in an IPX8 phone case for photos on the water.
This is the dry bag that got named one of the top dry bags by The NY Times Wirecutter, and it comes backed by a five-year warranty. The 500D PVC material with a roll-top seal is abrasion resistant, so it stands up to scrapes against rocks and boat decks. The included IPX8 certified phone case fits phones up to 6.5 inches and has dual clear windows, so you can snap photos from your kayak without pulling your phone out.
The straps vary by size: the 10L and 20L versions include a 24 to 42 inch adjustable shoulder strap, while the 30L, 40L, and 55L versions add backpack-style straps with a sternum strap. The 55L also throws in a heavy-duty waist belt for extra support. The whole thing rolls down small enough to stash on a boat or paddleboard, then unrolls fast when you need your gear.
Customers note the bag keeps everything dry even under pressure — one owner even blew extra air into it to use as a flotation device for a child who could not swim well. The 10L size comfortably fits a towel, shoes, snacks, and a change of clothes for a day trip. The phone case is a great bonus, though one buyer did lose a phone when the neck lanyard loop broke, so double-check the attachment before relying on it.
What wins people over
- Included IPX8 phone case with clear windows for underwater photos
- Backpack straps with sternum strap on larger sizes for comfort
- Abrasion-resistant 500D PVC handles rough conditions
Watch out for
- The phone case lanyard loop can break — check it before use
- Slightly heavy compared to ultralight nylon options
Best for: kayakers and paddleboarders who want a rugged, dependable bag plus a built-in way to use their phone on the water.
Look elsewhere if: you want the absolute lightest bag for backpacking — the PVC build adds heft.
6. Sea to Summit Lightweight Dry Bag
A low-profile 8-liter sack that kept a camera bone dry through 20 miles of heavy rain.
This is the bag for people who care about weight and packability. It is made from lightweight PU-coated 70D nylon with a DWR finish, and it weighs just 0.15 pounds. The interior polyurethane coating is white, which makes it easier to see your gear inside. The waterproof seams are double stitched and tape sealed, and the Hypalon roll-top closure keeps the seal secure.
The oval base resists rolling, and the low-profile shape saves space in a larger pack. A patent-pending field repair buckle can be replaced in seconds without tools. Buyers love it for bicycle trips — one cyclist did 20 miles in heavy rain and found everything in their pack soaked except the camera safely inside this bag. It also fits a 32oz Hydroflask, snacks, and a sandwich for a kayak outing.
The 8-liter capacity is right for a single person’s essentials or a camera setup. It does not come with a strap, so plan to use a carabiner or clip it to your board straps.
Featherweight reliability: At 0.15 pounds with taped seams, this is the go-to for cyclists and hikers who count every ounce.
No strap included: You will want a carabiner or clip to attach it to your pack or paddleboard.
Reach for this if: you bike, hike, or paddle and want a light, flexible bag that tucks away when not in use.
Think twice if: you need a shoulder strap built in, or you plan to carry more than a few essentials.
7. Pelican Waterproof Dry Bag 10L/20L/30L – Reflective
A rugged, reflective option from Pelican that holds up to waterfalls and rough use.
From the brand known for bombproof cases, this dry bag brings that same toughness to the water. The rugged, flexible construction is built to withstand the toughest conditions, and it stays waterproof in situations like standing under a waterfall. Reviewers point out not a drop of water gets inside, and the bag holds wallets, phones, keys, and even a jacket for two people.
The 30L version includes two padded backpack straps for comfortable, hands-free carrying over long distances, plus integrated loops and buckles to attach your essentials. The water-resistant front pocket offers secure, practical storage for small items while protecting them from the weather. It weighs 1.6 lb, which is substantial but manageable for the durability you get.
Owners praise it as far better quality than off-brand options — one sealed it empty and found it fully air and water tight, even holding their weight. It is also wipeable with antibacterial wipes, making it easy to clean after a muddy trip.
Built tough: The air-tight seal and rugged construction make this a dependable choice for fishing, hunting, and kayaking.
Size note: Sufficient for essentials but not huge — check the liter size you need before ordering.
Best for: anglers, hunters, and paddlers who want a durable bag with comfortable backpack straps and reflective visibility.
Look elsewhere if: you need ultralight gear — at 1.6 lb for the 30L, this is a heavier build.
8. Haimont IPX7 Waterproof Roll-Top Dry Duffel Backpack
A boat-sized duffel that survived a six-day whitewater trip without a single drop inside.
This is the serious multi-day bag. The IPX7 rating means it is protected against immersion in water up to 1 meter for 30 minutes, and the heavy-duty 500D tarpaulin with high-frequency welded seams delivers on that promise. It comes in 60L and 90L capacities, with a large waterproof main compartment, interior mesh pockets, and a quick-access front storage pocket for organized packing.
The roll-top closure seals out water while compression straps stabilize your gear. Multiple haul handles and convertible, adjustable backpack straps give you versatile carrying options — a feature that proved essential for portaging on a Canada fishing trip. Shoppers say it held enough gear for two people to survive several days, and it matched the performance of pricier dry bags on a whitewater rafting expedition.
The 60L version weighs 2.5 pounds and measures 13.78 x 22.83 x 22.44 inches. It is a perfect boat bag for a day at the beach or a full weekend outing, with several handles so you can carry it many ways.
Why it earns its spot
- IPX7 rating and welded seams keep gear dry even when submerged briefly
- Interior mesh pockets and front storage organize small items
- Convertible backpack straps make portaging and carrying easy
What to consider
- Straps get mixed feedback — some find them less comfortable for long carries
- Large size is overkill for quick day trips
Best for: multi-day rafting, camping, and motorcycle trips where you need serious capacity and IPX7-rated protection.
Think twice if: you only need a small bag for a day on the water — this is built for the long haul.
9. MIER Large Waterproof Duffel Bag – 60L/80L
A hurricane-ready 60L duffel that works as a backpack, a duffle, or a go-bag.
This bag is built for big loads and wet conditions. The 500D tarpaulin material with high-frequency welded seams is waterproof and sandproof, and the wide hook-and-loop-secured roll-top opening allows quick access. To seal it, you fold the top down 3 to 4 times and secure it with side clips for a snug, compressed fit. The note in the specs is important: do not submerge it in water.
The 60L version weighs just 3.3 lbs, which is remarkably light for the capacity. It features four compartments: a large main compartment, a water-resistant front zipper pocket, an internal zipper pocket for valuables, and two inner mesh pockets. The quick-release backpack straps with an adjustable sternum strap provide load stability, and multiple lash points let you secure it to a kayak, motorcycle, or roof rack.
Buyers report it still looks brand new after three years of use, and it holds a surprising amount of clothes while compacting well. It is also a solid choice for an emergency go-bag, especially in hurricane-prone or flood-zone areas. The dynamic height design means the bag can expand or compress to match your load.
Big capacity, light weight: The 60L capacity at 3.3 lbs is a standout combination for travel and camping.
Watch the closure: The Velcro-style hook-and-loop closure gets mixed reviews — some find it finicky, and the setup instructions are sparse.
Reach for this if: you need a large, versatile duffel for camping, emergency kits, or travel that can switch between backpack and duffle carry.
Look elsewhere if: you expect full submersion protection — this bag is waterproof and sandproof but not meant to dive.
Understanding the Specs
IPX Ratings
This is a quick way to know how wet a bag can get. IPX5 means it handles splashing and rain but not submersion. IPX7 means it can be immersed in water up to 1 meter for 30 minutes. IPX8 means it can go deeper or longer — like the phone case Earth Pak includes. Know your rating before you trust the bag in open water.
Material: PVC vs. Nylon vs. Tarpaulin
If you want maximum toughness against scrapes, PVC (a heavy, stiff plastic) is the material to choose. If you want light weight and easy packing, nylon (a synthetic fabric) works well but needs a waterproof coating to keep water out. Tarpaulin (a coated, heavy-duty fabric) sits in the middle, balancing weight and durability. Your choice depends on what matters more: carrying less weight or surviving rough use. A 500D rating (a measure of fabric density) means the material is denser and more resistant to abrasion, so it holds up better against rocks and rough surfaces.
