If you want one dry bag that just works, the STOVER 25L is the pick most people should buy. It pairs a heavy vinyl body and welded seams with a phone case thrown in, so your clothes and electronics stay dry on a river trip. Below you get eight real options, each matched to a 35-liter need using the nearest size that brand actually sells, so a couple of picks run 25L, 30L, or 40L instead of an exact 35.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
A dry bag only earns its place when the roll-top closes tight and the seams hold, so every pick here was checked for its closure and its material. If you are packing for a paddle or a river day, this list covers the 35l dry bag options worth your money.
Our Picks at a Glance
How To Choose The Best 35L Dry Bag
A 35L dry bag is the size that fits a solo weekend or a couple of day trips on the water. The catch is that brands sell slightly different sizes, so you often pick a 30L or a 40L and get close to the same job done. What matters is the closure, the material, and how you plan to carry it.
Start with the roll-top closure
The roll-top is the whole point of a dry bag. You fold the mouth over itself three to five times, then clip the buckle, and that folded material is what blocks water from getting in. Fewer rolls than the maker asks for is the most common way a bag leaks. A bag that seals with a simple buckle, like the HEETA, uses the same idea with a slightly different feel.
Look at the material and the seams
Most tough dry bags here use 500D PVC, a heavy waterproof plastic sheet measured in denier, where a higher number means a thicker, more scuff-resistant fabric. Welded seams matter too, because stitching leaves tiny holes that water can find. The best bags bond the seams with heat instead of thread.
Decide how you will carry it
Under about 20 liters, a single strap slung across your body works fine. At 30L and up, you want two shoulder straps so it rides like a backpack, especially if you fill it with towels and clothes. A padded back and a chest strap cut the strain on longer walks to the water.

In-Depth Reviews
1. STOVER Waterproof Dry Backpack & Phone Case
Our pick — over 4.5★ from 700+ verified ratings; the strongest balance of quality and price.
The do-it-all river bag that throws in a waterproof phone case for free.
Buyers consistently praise the heat-bonded seams and floating body. High-frequency seam bonding (heat-fused seams rather than stitched ones) keeps water out, and the bag floats if it ends up in the water. You get three ways to carry it: two shoulder straps for a backpack, one strap across your body, or the over-molded top handle at your side. That range is rare at this size.
It comes as the nearest sold size, 25L, which is the brand’s stand-in for a 35-liter need. A removable wet/dry mesh front pocket holds small items, and the reflective strip on that pocket helps a boat or car spot you in low light. The included phone case is IP58 rated — that means it blocks dust and splashing water — and fits phones up to 6.5in x 3.2in.
Buyers report it swallows three towels, sunscreen, clothes for three people, plus spare phones and a solar charger. That is a lot of packing for a 25L bag, and it is why this is the crowd favorite at 4.6 stars across 700-plus owners. Buyers rave about the welded PVC build, with the 25L capacity a close second.
What riders keep praising
- Heat-bonded seams and a floating body keep gear dry on tubing and paddling days
- Three carry modes — backpack, cross-body, or top handle
- Reflective strip plus a bundled IP58 phone case add safety and value
Where it stumbles
- Strap placement draws the most mixed feedback — a few say they want wider straps and a few report missing straps
- Waterproofing is not sold as full-submersion rated, so keep the top rolled tight
Best fit: anyone who wants one bag for tubing, kayaking, and beach days with an included phone case.
Think twice: if you need a no-doubt submersion bag for diving, look at the IDRYBAG below instead.
2. YUMQUA Roll Top Floating Dry Bag
A tough 40L paddling bag that punches well above its entry-level sticker.
You get the largest bag of the group here. The body is 500D PVC, a thick waterproof material measured in denier, and the seams are fully welded rather than stitched, so there are no needle holes to leak.
The 40L size comes with double detachable straps so it wears like a backpack. Owners mention it keeps a full set of snorkel gear dry and holds three people’s beach stuff with room to spare. Owners sum up the value: “5L dry bag kept items completely dry during 7-hour tubing trip.”
Buyers praise the welded 500D PVC build most, with water resistance a close second. The brand also sells 5L, 10L, 20L, and 30L versions, so you can buy small for a day hike or go big for a trip. Just roll it three to five times and leave a little air inside so it floats better.
Pick this if you want the most room per dollar: at 40L it carries the biggest load here, and the welded PVC construction holds up on repeated dunkings.
Honest caveat: durability is a mixed note in the review pages, with some owners calling it solid and a few reporting trouble, so treat sharp rocks and rough concrete gently.
Reach for this if: you need maximum capacity and a true backpack carry without moving up a tier.
Look past it if: you want a built-in phone case or a front pocket for keys — the STOVER covers both.
3. HEETA Waterproof Dry Bag Backpack with Zippered Pocket
A 30L backpack built around a zip pocket you can reach without unrolling the top.
The standout is that front splash-proof zippered pocket. Instead of unrolling the whole bag every time you want your keys or a credit card, you just unzip and grab. The body is a triple-layer PVC: a durable PVC inner layer, a patch-mesh middle layer, and a reinforcement outer coating, with the whole thing measuring 0.02in (0.5mm) thick. That combination is what makes it wear-resistant and scratch-resistant.
You get a 30L bag — the brand’s closest size to the 35L you’re after. The roll-top (a top you fold down and clip shut to keep water out) seals with a secure buckle, and the bag floats if you drop it in the water. The shoulder straps adjust and come off when you don’t want them. Customers note fitting two rolled-up towels, sunscreen, a wallet, and flip-flops inside, and capacity is among the most-mentioned positives in the reviews.
Just note the maker labels it for surface sports like kayaking and rafting, not underwater use, so it is not meant for submersion. Pair it with a simple strap for short trips, or the double-strap backpack setup for a full day on the water.
Why owners grab this one
- Front zip pocket for fast access to keys, cash, and cards
- Triple-layer 0.5mm PVC holds up to scuffs and weather
- Adjustable, removable straps and a floating body
Fair warning
- The front pocket is small — a phone might not fit, so plan for keys instead
- Rated for surface water sports only, not underwater use
Go here for convenience: the zip pocket means no unrolling just to grab your car keys on a paddling break.
Skip if you plan to fish your phone out of that pocket — it is sized for keys and cards, not most phones.
4. GVANCA Roll Top Kayak Dry Backpack 35L
The true 35L that a two-to-three day water trip was built around.
This one is genuinely 35 liters, the exact size you searched for. The brand calls it great for a two-to-three day trip on the water, and the 55L and 85L siblings scale up to a week and a family respectively. The body is 500D PVC, a heavy waterproof fabric, and the bag passed a full-immersion test according to the maker.
The harness is the real story. You get wide, thick shoulder straps, a movable chest strap, and a detachable waist strap, all adjustable to your height and weight. The chest buckle doubles as an emergency whistle, and three separated air cushions pad your back. Reviewers point out it comfortably fits a small sleeping bag, and one used it on a week-long summer campout canoe trip down a river.
What is worth flagging: this is a pack first, a dry sack second. A few owners wanted more mounting points for a bike rack, so if you plan to lash it to a motorcycle, measure your tie-down options first.
The full 35L option: no nearest-size compromise here — get the actual capacity if that is what you need.
Watch the mounting: some buyers wanted better rack attachment for motorcycle use, so it is best for carry-on-back trips rather than strapped luggage.
Ideal for: paddlers who want a real 35L pack with a waist strap, chest strap, and back padding for multi-day trips.
Not built for strapping to a bike rack — a few owners found the lack of mounting points a hassle, so pick it for backpack carry instead.
5. iculbag Waterproof Backpack for Travel
A 30L waterproof pack that thinks of itself as a commuter bag too.
This is the pick that crosses over. The interior holds a large 30L load, which the brand says covers about three days of clothing for a short trip. There is one main pocket plus one interior pocket for valuables, a front mesh pocket with a drawstring, and a storage pocket on the left side. A back pad and lumbar pad take the weight off your shoulders, and a waist buckle keeps it locked to your body.
It weighs 1.32 kg, which is heavier than the ultralight packs here — the trade-off is that padding. Shoppers say it fits two laptops plus tools, a mouse, cables, an umbrella, and a jacket, and that it kept gear dry in normal and light rain. Buyers praise the padded back and the roomy 30L interior most.
The catch is interior organization: only one pocket inside, so small items can get lost. A few owners wish for zip pockets inside for smaller items, and the top-opening design is slower to get into if you pass through security checks often.
The travel case
- Back and lumbar padding plus a waist buckle for weight relief
- Four compartments including a front mesh pocket and a security side pocket
- Holds two laptops and gear in light rain
The fine print
- Only one interior pocket, so small items can get lost
- At 1.32 kg it is on the heavier side for a 30L bag
Suits the traveler: someone who wants one bag for flights, ATV rides, and wet-weather commutes with real back padding.
Pass on it if: you want lots of internal pockets to sort small gear — this keeps things simpler.
6. IDRYBAG Submersible Waterproof Backpack 35L
An IP-68 submersible 35L built to survive a full dunking.
IP-68 is the highest water rating you will see on a dry bag — it means the bag is designed to keep water out even when fully submerged. The brand backs that with high-frequency stitching that leaves no pinholes. Where the others here are built for splashes and floating, this one is built for going under, and it is a true 35L.
The extras are aimed at hard-water use. A removable belt lets you lash it to the hull of a boat or kayak so it does not wash away in rapids. There are three compartments, including a separate orange inner pocket to protect valuables, plus MOLLE loop straps for attaching gear and reflective strips on the bottom for low-light visibility. A chest buckle and waist belt with an emergency whistle round out the harness.
Buyers single out the appearance most, with the IP-68 water resistance close behind. Buyers report a 55L version keeping gear bone dry through hours of heavy rain on a motorcycle trip. One honest note: at 2.4 pounds the straps are on the thinner side, and a few owners found them less comfortable over long carries.
The submersion choice: when the bag may go under, IP-68 and sealed stitching matter more than anything else on this page.
Sizing tip: owners mention it runs larger than expected, so if a long paddle is rare for you, the 35L is plenty and the 55L is a lot of bag.
Best when water is serious: rafting, canoeing, or any trip where the bag may fully go under.
Skip if you mostly carry short distances — the straps are thinner than the padded options here and get less comfortable loaded down.
7. OSAH DRYPAK Waterproof Roll-Top Backpack 35L
A 35L hiking-first pack with pockets, bungee cords, and real back padding.
This one leans into comfort and organization more than most. You get ergonomic shoulder straps, breathable back padding, a reinforced top handle, and an adjustable chest belt with a safety whistle. The body is 500D PVC with high-frequency welded seams and a roll-top closure — the same waterproof recipe the best bags here use, in a true 35L.
It carries smart features for the money: inner zip pockets, side mesh bottle holders, a splash-proof front pocket, and elastic bungee cords for a jacket or sandals. A reflective strip, D-ring attachment points, and a carabiner hook help on the trail. Buyers have taken it through the Boundary Waters Canoe Area on a five-day expedition and used it for off-road, rafting, and jet-ski trips, and the size suits a family of four for a day float.
The honest trade-off is sealing: some owners say the top does not close tightly. That is the most-discussed mixed point in the reviews — some owners call it great in rain while others say the top does not seal tightly and water gets in. Roll it and clip it carefully every time.
Standout strengths
- Padded back, chest belt, and safety whistle for long days
- More pockets than any other pick — inner zip, mesh bottle, front, plus bungee
- Proven on week-long canoe expeditions
Needs care
- Water resistance splits buyers — a few found the top does not seal tightly
- A padded waist strap would help when the bag is fully loaded
Ideal if you want the most features: padded harness, whistle, extra pockets, and bungee cords make it the day-pack of the group.
Think twice if reliable sealing is your top priority — roll and clip it carefully, as some owners found the top less watertight.
8. NRS Tuff Sack Dry Bag 35L
A no-straps 35L sack for stuffing into a canoe or a pack.
This is the old-school option: a 35L sack with no shoulder straps, so you pack it inside another bag or strap it down. The body is 18 oz PVC and polyester, a heavy waterproof material, with welded seams and a fold-down StormStrip closure — a reinforced strip you roll and buckle. A quick-release buckle handles the seal, and a single D-ring offers one tie-down point.
Owners have run it through a three-plus hour torrential downpour on the Northern Tier Trek in Minnesota and pulled out dry contents. Others fill it with tents, sleeping bags, and pads. The brand is clear about what it is: waterproof, foldable, and made of sturdy material.
The honest trade-off is wear at the fold points over time. That is a mixed note in the reviews — the material is tough, but a few customers note wear and tear at the fold points after months of use. Roll gently and it should hold up.
Who it is for: canoeists and travelers who want a bare, dependable 35L sack with no straps to fuss over.
Expect to lash it yourself: there is only one D-ring, so if you want to secure it in a boat, come prepared with your own straps.
Good for the minimal packer: a tough, welded-seam 35L sack that slips into any canoe or duffel.
Not for carrying on your back — with no shoulder straps and just one D-ring, it is meant to be packed or strapped, not worn.
Understanding the Specs
Roll-Top Closure
The roll-top is the seal. You fold the mouth over itself three to five times and clip the buckle, and the folded layers are what stop water from entering. Bags here ask you to roll anywhere from 2-3 to 3-5 times, so follow the maker’s count. A quick-release buckle, like the one on the NRS Tuff Sack, makes it fast to open and close.
500D PVC And Denier
Denier is a measure of how thick and heavy a fabric is — a higher number means a tougher sheet. Many bags on this list use 500D PVC, a heavy waterproof plastic. The HEETA pushes further with a triple layer totalling 0.02in (0.5mm) thick, and the NRS uses an 18 oz PVC and polyester blend. Thicker material resists scuffs and tears better.
IP Ratings Explained
An IP rating tells you how well a product keeps out dust and water. The higher the second number, the more water protection. The IDRYBAG carries IP-68, the highest for water — it is built to keep water out even when submerged. The STOVER’s bundled phone case is IP58, which covers dust and splashing water.
Capacity And Carry
Capacity is measured in liters. A 35L bag suits a weekend or a couple of day trips. Small bags under 20L often use one strap slung across the body, while 30L and up usually come with two straps so they wear like a backpack. If you plan to walk far, look for padded straps, a chest belt, and back padding.

Final Thoughts: The Verdict
For most people, the 35l dry bag winner is the STOVER Dry Backpack, because it combines heat-bonded seams, three carry modes, a reflective strip, and a bundled IP58 phone case in one value-packed bag. If you need the true 35L with a waist and chest strap for multi-day trips, grab the GVANCA Roll Top Kayak Backpack. And for water that may fully go under, the IDRYBAG Submersible 35L is the one to reach for. Whichever you pick, roll the top the number of times the maker asks, and your gear will come out dry.
