Best Waterproof Backpacks For Hiking – 2026 Reviews
Let’s be honest. There’s nothing that ruins a great hike faster than opening your pack to find a soggy sandwich, a waterlogged phone, and a change of clothes that feels like you pulled it from a washing machine. I’ve been there, staring at a drenched map while the rain just keeps coming. It’s a special kind of misery. That’s why finding the right waterproof backpack isn’t just about convenience-it’s about saving your trip, and your sanity.
The tricky part? ‘Waterproof’ can mean a lot of different things. You’ve got the hardcore, roll-top dry bag style that you’d trust in a kayak, and then you’ve got the more traditional hiking packs that come with a rain cover tucked in a bottom pocket. Both have their place, depending on whether you’re fording a stream or just trying to outrun an afternoon thunderstorm. I’ve tested a bunch of them to cut through the marketing and find what actually works when the clouds open up. Here’s my breakdown of the best waterproof backpacks for hiking, from bombproof submersible bags to brilliantly designed lightweight daypacks.
Best Waterproof Backpacks for Hiking – 2025 Reviews
Earth Pak Waterproof Backpack – Heavy Duty Hiking Backpack
If your definition of hiking involves getting soaked-think river crossings, kayak portages, or relentless Pacific Northwest drizzle-this is your pack. The Earth Pak isn’t just water-resistant; it’s a true submersible dry bag with a roll-top closure that creates an airtight seal. Beyond the waterproofing, it’s built like a tank with a super comfortable, padded back panel and a MOLLE system for extra gear.
Maelstrom 40L Hiking Backpack with Rain Cover
This pack hits the sweet spot for most hikers: fantastic organization, a super-comfortable carry, and a reliable included rain cover that stows in its own dedicated pocket. The Maelstrom 40L feels thoughtfully designed, with a hydration sleeve, trekking pole attachments, and even a survival whistle on the chest strap. It’s the versatile workhorse that makes weekend trips effortless.
STOVER Waterproof Dry Backpack & Phone Case
For sheer waterproof bang-for-your-buck, it’s hard to beat the STOVER Dry Backpack. Like the Earth Pak, it uses a reliable roll-top closure for total dryness, but it comes in a huge range of sizes (from 5L to 55L) and includes a bonus waterproof phone case. It’s a fantastic, no-fuss solution for wet-weather hikes, beach trips, or as a packable emergency dry bag inside a larger pack.
Trudave Waterproof Submersible Floating Backpack
This is a specialist. The Trudave backpack is built from TPU (a premium dry bag material) and features a fully airtight waterproof zipper, not a roll-top. It has a rigid, breathable back panel and includes an air valve so you can inflate it slightly to ensure it floats high in the water. It’s the go-to for scuba divers, serious kayakers, or anyone whose hike might end with an unintended swim.
G4Free 40L Lightweight Packable Hiking Backpack
This is the ultimate backup bag or minimalist daypack. The G4Free Packable Backpack folds into its own pocket, weighs almost nothing, yet offers a clever separate waterproof ‘wet pocket’ on the back. It’s perfect for travelers, as a surprise-weather daypack in your luggage, or for fast-and-light hikes where you want to keep sweaty clothes or a wet swimsuit isolated.
Loowoko 50L Hiking Backpack with Rain Cover
A great option for longer day hikes or short overnights, the Loowoko 50L offers a great balance of capacity and comfort for its class. It includes a rain cover stowed in the bottom and features a well-ventilated back system and a handy separate shoe compartment, making it ideal for multi-activity trips.
WoneNice 50L Waterproof Hiking Backpack
Another solid contender in the large-capacity, rain-cover-equipped category, the WoneNice 50L is praised for its clear internal layout and overall value. It’s a simple, effective pack with a comfortable S-curve shoulder strap design and plenty of pockets to keep your gear sorted on weekend adventures.
Nerlion 40L Hiking Backpack Travel Backpack
The Nerlion 40L is a sleek, modern-looking pack that blends hiking and travel features. It includes a hidden anti-theft pocket on the back and a luggage strap for slipping over a suitcase handle. Its water-resistant nylon construction is lightweight, and it’s designed to be a versatile single bag for a variety of activities.
Our Testing Process: Why These Rankings Are Different
When I started this review, I had one question: which packs actually keep stuff dry? It sounds simple, but it’s not. We began with a pool of 10 popular waterproof and water-resistant hiking packs to find out. I don’t just glance at spec sheets; I judge based on real-world performance (70% of the score) and smart, unique features that set a pack apart (30%).
Performance means actually getting caught in the rain, simulating a bag taking a dunk in a stream, and seeing how easy it is to access gear when the weather turns. Features are about clever design-like the G4Free’s separate wet pocket or the Trudave’s airtight zipper-that solve real hiker problems.
You can see this scoring play out in the rankings. The top-rated Earth Pak scored a 9.8 for its bombproof, submersible performance and great comfort. Our Budget Pick, the STOVER, scored an 8.8. That 1.0 point difference is the trade-off: you get the same 100% waterproof guarantee for a much friendlier price, but with slightly less trail-optimized comfort for heavy loads. A 9.0+ score means Exceptional and highly recommended; an 8.0-8.9 is Very Good and a solid choice with clear value.
My goal is to cut through the hype. I’m not here to sell you the most expensive bag, but to help you find the right bag-whether that’s a premium dry bag for kayak hiking or a brilliant budget pack that stows in your jacket. The scores reflect what actually matters when you’re on the trail and the sky opens up.
Complete Buyer's Guide: How to Choose a Waterproof Backpack for Hiking
1. Waterproof vs. Water-Resistant: Know the Difference
This is the most critical choice. A truly waterproof backpack (like the Earth Pak or STOVER) uses a roll-top or airtight zipper system and is made from sealed materials like TPU or PVC. These are submersible-they’ll keep your gear dry even if the pack goes underwater. They’re essential for canoeing, pack rafting, or hiking in consistently pouring rain.
A water-resistant backpack with a rain cover (like the Maelstrom or Loowoko) is made from treated nylon or polyester. It will shed light rain, but in a heavy downpour, water will eventually seep through the seams and zippers. The included rain cover is your primary defense. This is perfect for most trail hiking where you might encounter rain, but aren’t planning to be in the water.
2. Capacity: How Much Gear Are You Carrying?
Daypacks (20-35L): Great for short hikes, photography gear, or as a packable backup. The G4Free is a star here.
Weekend Packs (40-50L): The sweet spot for 1-3 night trips. Packs like the Maelstrom 40L and WoneNice 50L offer perfect balance.
Expedition Dry Bags (50L+): For multi-day water-based adventures. The larger STOVER or Loowoko 50L models fit this need.
Always remember: a roll-top dry bag’s capacity can be adjusted by how much you roll it down, giving you flexibility.
3. Comfort & Fit: It Has to Carry Well
Waterproofing is useless if the pack is miserable to wear. Look for:
Padded, Contoured Shoulder Straps: Wide, S-curve straps (like on the WoneNice) distribute weight better.
Ventilated Back Panel: Mesh padding (on the Maelstrom and Loowoko) prevents a sweaty back.
Sternum Strap & Hip Belt: Essential for stability. A good hip belt (like the Earth Pak’s) transfers weight to your hips, saving your shoulders.
Always adjust all straps! A properly fitted pack makes a world of difference on mile 10.
4. Organization & Access: Where's Your Stuff?
Think about how you hike. Do you need constant access to snacks, a rain jacket, or your phone?
Traditional Top-Loaders: Common on hiking packs. Great for maximizing space, harder to access items at the bottom.
Panel-Loading or Multiple Access Points: Zippers that open the front or side of the pack (like on many travel-style packs) make organization and access easier.
External Pockets: Look for stretchy side pockets for water bottles, easy-access front pockets, and especially hip belt pockets-they’re a game-changer for snacks, lip balm, and your phone.
5. Durability & Features for the Trail
The trail is tough on gear. Consider:
Material: Cordura nylon or high-denier polyester is tough and abrasion-resistant. TPU (like on the Trudave) is incredibly tough and flexible for dry bags.
Hydration Compatible: Does it have a sleeve for a water bladder and a port for the hose? The Maelstrom has this built-in.
Attachment Points: Daisy chains, ice axe loops, or compression straps (like on the Loowoko) let you carry trekking poles, a sleeping pad, or other bulky items outside the pack.
Your backpack is your partner on the trail. Choosing one with the right mix of these features will make every hike more enjoyable, rain or shine.
Frequently Asked Questions
1. Can I just use a regular backpack with a rain cover?
Absolutely, and for many hikers, this is the perfect solution. A quality rain cover (like the ones included with the Maelstrom or Loowoko packs) will protect a water-resistant backpack from heavy rain remarkably well. The key advantage is that you get the comfort, ventilation, and organization of a dedicated hiking pack. The trade-off is that it’s an extra step when the rain starts, and it doesn’t protect against submersion or water pressure (like if you slip and fall in a stream). For most trail hiking, a good pack + a good cover is all you need.
2. Are waterproof backpacks less breathable?
Often, yes. This is the classic trade-off. A fully waterproof material like TPU or vinyl doesn’t breathe at all, which can lead to a sweaty back. However, many modern dry bag backpacks (like the Earth Pak and Trudave) now incorporate padded and breathable back panels and shoulder straps to mitigate this. On the other hand, traditional hiking packs with rain covers are typically made from breathable mesh and fabrics, so they’re much more comfortable in warm weather-you just have to remember to deploy the cover when it rains.
3. How do I clean and maintain a waterproof backpack?
For roll-top dry bags (Earth Pak, STOVER): Rinse with fresh water after saltwater or muddy use. Avoid harsh chemicals. Let it air dry completely unrolled and open to prevent mold and mildew. For the rubber gaskets on airtight zippers (Trudave), you can occasionally wipe them with a silicone lubricant to keep the seal supple.
For water-resistant hiking packs with rain covers: Most can be spot-cleaned with mild soap and water. The rain covers can usually be hand-washed. Always check the manufacturer’s instructions, and never put a backpack with a waterproof coating in a dryer, as the heat can damage the treatment.
4. What size backpack do I need for a day hike vs. an overnight trip?
For a summer day hike with just the essentials (water, food, layers, first-aid), a 20-30 liter pack is usually plenty. The packable G4Free is great for this. For a 1-3 night backpacking trip where you’re carrying a sleeping bag, pad, tent, and food, you’ll typically need a 40-50 liter pack, like the Maelstrom or Loowoko. Remember, if you’re using a roll-top dry bag, you can often size down slightly because they are more efficient at compressing soft gear and have no internal frame to take up space.
Final Verdict
Choosing the best waterproof backpack comes down to matching the level of protection to your actual adventures. If your hikes are more like expeditions where your gear will get wet, the absolute security of a Earth Pak dry bag backpack is worth every penny. For the vast majority of trail hikers who want fantastic comfort, organization, and reliable rain protection, the Maelstrom 40L with its integrated rain cover is the perfect, versatile workhorse. And if you’re on a tight budget or want a brilliant backup, the STOVER Dry Backpack offers incredible submersible protection at a bargain price. No matter which you choose, you’re taking a big step toward drier, happier, and more confident days on the trail.
