Now you can get a very comfortable all day pack that has the same submersible capabilities as the best dry bags.

We’ve put together a list of some of the best waterproof backpacks across the spectrum of price, capacity, and capability to help you narrow down your search.

The thing that really helps set the Overboard Pro-Sports backpack apart is the carry options. It has padded shoulder straps and lumbar support that makes it very comfortable to wear. Each strap also has a reflective coating to make it more visible at night.

Sea to Summit Flow Drypack

Buy from Amazon

Sea to Summit makes some of the best dry bags, travel gear, and outdoor equipment available. The Sea to Summit Flow DryPack is a 35l waterproof backpack designed for the true outdoorsman.

It’s made from highly water resistant 420D TPU laminated nylon with fully sealed seams. It uses a roll top closure and has buckles and strap holds made from aircraft grade alloys. This gives the DryPack substantial strength and durability wherever life takes you.

It honestly looks a lot more like a weekend hiking pack than a standard roll top dry bag. The only real downside to the DryPack is its price, frequently well over $200.

If you’re planning to do some serious hiking, skiing or snowboarding the Sea to Summit Flow DryPack is a great option. It’s fully waterproof and ergonomically fitted to be comfortable for all day wear.

FE Active 30L Eco Friendly Waterproof Backpack

Buy from Amazon

The FE Active is an eco friendly waterproof backpack with a 30l capacity. It’s made from 5mm PVC from eco friendly sources.

It has a padded back and breathable straps for all day comfort and provides you with several storage options. There’s the waterproof main pocket with a roll top closure of course, but there are also a few other outside access pouches.

The front of the pack has a set of adjustable bungee cords that allow you to strap down jackets, hats, and other items you don’t mind getting wet. On either side is a mesh pocket great for holding water bottles and similar items.

We really liked the inclusion of a chest strap. It makes sure the bag isn’t going anywhere, even over rough terrain.

The FE Active Eco Friendly 30l isn’t the best waterproof backpack out there. Given it’s very affordable price and good range of features though, it’s not a bad choice if you’re looking for a value waterproof backpack.

Buyer’s Guide to Buying the Best Waterproof Backpack

There are a lot of factors to consider when picking out the best waterproof backpack. The most important ones are price, waterproofing, closure type, and ergonomic features.

As long as you find the right mix of these features you’ll end up with a bag that fills your needs and won’t let you down.


There’s a big range of prices in the waterproof backpack field. They start at around $40 and can go up to several hundred for a feature packed bag from a well known brand.

Price doesn’t always equal quality of course, but for the most part the best waterproof backpacks will run above $100.

Level of Waterproofing

Waterproof fabrics are measured using hydrostatic head. This measures how many mm of water pressure a specific fabric can withstand before water starts to seep through. Unfortunately it isn’t as useful a measure as we might like.

Not all waterproof backpack manufacturers provide the hydrostatic head of their products, and even when they do it doesn’t always take into account things like seams, stitches, and the type of closure they use.

Type of Closure

In just about every waterproof backpack the closure is going to be the point of failure. If you need a really waterproof bag a roll top closure is the most commonly used.

This works with a rigid strip of plastic embedded inside the rim of the opening. There’s an internal space you can fill plus several inches of extra closure material.

To seal your bag you roll the top several times into itself then clip it securely closed on the ends. This type of seal helps prevent water from entering when splashed or with a quick dunk.

Bag Capacity

Waterproof backpacks have a pretty consistent range of sizes. 20l up to about 35l is the norm, about the size of a large daypack or weekend hiking bag. You can definitely get waterproof backpacks that are bigger than this, all the way up to large waterproof duffel bags with backpack straps.


Waterproof backpacks all have at least a pair of back straps and a carry handle near the top. Roll top backpacks and other similar

Additional Storage And Pocket Options

Some waterproof backpacks are little more than dry bags with a pair of shoulder straps. They offer a single large compartment to store clothes and other items you want to keep dry, but not much else.

As you move up the quality and price scale more features begin to pop up. Some of the best waterproof backpacks have multiple interior zipper compartments, outside access sleeves/pockets, and things like camelbak reservoir slots.


As with any piece of gear designed to be carried around for long periods less is more when it comes to weight. Try to balance out the weight of your bag with the features you need.

Generally speaking, the more options and capabilities a bag has the more it will weigh. If you’re willing to spend more though you can get highly capable bags that are lighter than you’d believe.

Reinforced/Welded Seams

One of the most common failure points for any bag is the seams. With waterproof backpacks the gold standard is laser welded seams. These create a perfect seal between pieces of fabric that prevent any water from penetrating.

A good alternative commonly seen in value priced waterproof backpacks are taped seams. These provide good waterproofing but aren’t quite as durable or effective as welded seams.


The material used to make a waterproof backpack depends on what level of protection you need. If you’re going white water rafting or want to take your backpack out on the open seas, PVC and TPU laminated nylon are the materials of choice.

These are totally waterproof and can actually provide submersible protection when paired with the right type of closure. If you’re just out hiking in wet conditions or want a day pack that can stand up to the occasional rain shower something like DWR coated nylon or polyester will work just fine.


One of the most important factors to keep in mind is how long your waterproof backpack will last. Material and workmanship will place the biggest role here, with material affecting overall durability the most.

PVC is a very sturdy material that has excellent waterproof properties. Unfortunately, it’s also susceptible to damage from UV exposure of the sun. Over time it becomes less impact resistant and overall more likely to tear.

Workmanship also plays a big role. Stitching, welded seams, and the types of hardware used for straps will affect how well it holds up.

Intended Use

Probably the biggest factor in picking out the type of waterproof backpack you need is how you intend to use it. If you’re participating in water sports like surfing, rafting or boating you’ll need a lot more protection than if you’re out hiking in wet conditions.

Fully waterproof bags are available, but they often lack the external attachment points, multiple access pockets, and overall style of water resistant backpacks. They can also be less comfortable on your back because they lack things like foam padding on the straps and back.

Other Styles of Waterproof Bags

Waterproof backpacks are just one type of waterproof bag available to you. Depending on what you’re carrying and where you’re going there may be a better option available.

Waterproof Phone Pouches – Waterproof phone pouches are small resealable pouches made from transparent plastic with a water tight seal. They’re designed to protect your phone or tablet from the water and usually come with a lanyard or other attachment point so you don’t drop it.

Waterproof Dry Bag – A dry bag is basically a catchall term for any bag designed to keep goods safe from the water. In the past this included things like oilcloth and leather pouches, but now usually refers to a small (up to about 50ish liters) bag with a roll top closure made from PVC or TPU laminated nylon.

Waterproof backpacks have a lot of similarities with dry bags, with several basically being high-quality dry bags with backpack straps.

You can find bags that are well over a 100 liters in capacity, plenty of space for a weeks gear on a rafting trip. Some waterproof duffel bags will have backpack straps, blurring the line between the two categories.

Waterproof Camera Bags – Cameras are some of the most expensive and delicate pieces of gear you’ll take with you into the backcountry. Because of this waterproof camera bags have to provide reliable and comprehensive protection.
