Best waterproof backpacks for 2025: Tested in storms, torrential rain, and wild mountain weather

It's safe to say we are thoroughly impressed by the Transporter WP pack. The materials are instantly recognisable as high quality; Osprey have used bluesign approved 400D recycled nylon, which is TPU double coated to make it extra strong and durable.

That same nylon is used on the main outer walls and the base of the pack in one big piece of fabric, meaning there are no weak points for water to attack. After 12 hours of hammering from Babet, the sleeping bags we stuffed inside this bad boy were still bone dry.

The waterproof rating of IPX6 is about as high as you can go without something being designed to be fully submerged. So when you factor in the clippable roll-top closure, what you’re effectively getting here is a big waterproof sack with durable and protective outer walls that you can fully seal up.

This is one of those backpacks that somehow feels larger than its 30-litre capacity. Probably because the opening is so big and the fact that the inside is pretty much just one large sack-like compartment. But it does also have some nice pockets.

On the front of the pack, you get a large stretchy fabric sleeve that’s perfect for stashing things like wet waterproofs or gloves and hats. There’s also a small zipped pocket under that stretchy fabric on the outside, as well as a laptop sleeve inside.

And, on top of everything else, this pack is comfortable to wear, which is especially rare amongst waterproof backpacks. It comes fitted with Osprey’s renowned AirScape back panel, which is well padded with foam and covered with a webbed mesh that allows air to flow between the rear of the pack and your back.

The Osprey Transporter WP 30 is the standout waterproof backpack we’ve tested this year. It does the most important job of keeping its contents dry and protected from the elements brilliantly, but the good news doesn’t end there. It’s tough, comfortable and comes with enough impressive features to justify its high price tag. This is a fantastic bit of kit.

the Exped Typhoon 25 is a great low-priced option if you’re looking for a reliable waterproof hiking backpack that doesn’t need to perform on the toughest terrain or in the worst weather.

What Exped have produced here is a lightweight, reasonably robust and stylish waterproof pack with a good roll-top closure. It's ideal for use on day trips for everything from hiking and cycling to climbing and commuting.

Exped don’t make any overly bold claims about the Typhoon’s waterproofing capabilities, but from our testing experience the performance is very solid in terms of keeping the contents of the pack dry.

There are plenty of nice little features on this pack too. We like the gear attachments, the mesh back panel, and the inner lining that you can turn inside out and pull out of the pack for quick drying. 

In all, the Exped Typhoon 25 is a good choice if you’re looking for excellent value and reliability in an everyday waterproof backpack. The waterproofing is good, it has some really nice and useful features, and it looks great. Plus, you can choose from four colours (dark lava, coral, lichen and bluebird).

If you close your eyes and visualise a heavy-duty, technical, waterproof pack, it probably looks a lot like the Ortlieb Atrack 35. It’s the kind of backpack you’d expect to see Bear Grylls emerging from the Amazon undergrowth wearing.

Immediate highlights include its wear and tear-resistant fabric, an adjustable back system to suit your height, padded shoulder straps and back panel, and a heavy-duty and large zip opening that runs down the whole length of the back of the pack. And, the star of the show, an excellent IP67 waterproof rating.

That rating, in layman’s terms, means it’s hard to puncture with sharp objects and can even cope with short periods of immersion in water without letting anything seep through the fabric.

The comfort level of this pack is what sets it apart from the Osprey Transporter and the Sea to Summit Rapid, which have a roughly equal waterproof rating. The Atrack is excellently padded, and feels very much like a normal hiking pack (once everything is adjusted and tightened).

The first thing we thought when we picked up the Montane Trailblazer 28 was ‘wow, this is light’. So light, in fact, that on first impressions we didn’t think it could possibly match up to its competitors on the waterproof backpack scene.

Luckily, our scepticism was quickly put to rest. What Montane have created here is a hiking daypack that ticks a huge number boxes for lightweight devotees. The side-clipping roll-top closure is clever, the waterproofing seems good, the comfort is impressive, and the capacity of this 28-litre version is plenty big enough for long days on the trail.

When fully loaded, the comfort levels of the Montane Trailblazer 28 are good. The hipbelt harness is deep and lightly padded with a mesh backing, so it hugs your body and absorbs some of the weight you’re carrying.

That same mesh from the harness extends up into the back panel and shoulder straps, which are both also lightly padded, to create a bit of airflow and breathability when it’s flush against your body.

The roll-top closure works well – the advice from Montane is to roll it over three times before clipping and tensioning down the side of the pack. There’s also a hydration bladder sleeve sandwiched between the Trailblazer’s main chamber and the back panel,

In all, this pack is ideal for any fastpacker or even trail runner looking to carry their essentials in unpredictable weather. It’s loaded with impressive technology and available in a huge range of sizes to suit every type of trip.

This is the second generation of the Gourdon we’ve tested, and we’re pleased to report the first one is still going strong after six years of weekly use. There’s nothing overly groundbreaking to report in terms of features – this is basically a big no-frills waterproof sack with a roll-top closure that seals it up effectively from the elements. 

The outer material is quite lightweight and thin, but in our testing experience it does the all-important job of keeping water out – in the kind of conditions you’d expect on a standard British hike or hillwalk. We’ve used a slightly older version of the Gourdon (the Gourdon 30L) for more than six years and it’s never let us down.

In terms of comfort, we’d probably describe the Gourdon as more of a waterproof dry bag with shoulder straps than a full-on waterproof rucksack. that said, there is some padding on the shoulder straps and a thin protective layer on the back panel.

The hipbelt is just a thin adjustable strap that doesn’t offer a lot of support, but when you tighten everything it’s well-fitting and comfort isn’t an issue.

In all, the Gourdon 25 won’t win many awards for futuristic innovation, but if all you’re looking for is a well-priced waterproof sack that will keep your kit dry on wet hikes, then you can’t go far wrong with this.

There's a certain beauty in the simplicity of this pack. Sea to Summit have always excelled at making dry bags and stuff sacks, and they've clearly brought that expertise to the Rapid 26L. If you a picture a big dry bag with bombproof fabric, adjustable straps, a padded back panel, and a simple roll-top closure, you’ll come pretty close to what we've got here.

The Rapid 26L Dry Pack is constructed from 420D laminated nylon fabric with a hydrostatic head of 10,000mm. Sea to Summit describes this as waterproof and abrasion resistant, and the fact that 420D nylon is considered good enough for everything from gazebos and three-season tents to paddleboarding equipment tells you a lot about the quality of the materials used here.

The rolltop closure is excellent too. It rolls over really easily, then clips at the sides rather than across the top so you can easily access the carry handle. This also makes the closure feel very secure, adding a further barrier to any potential water ingress.

As with most stripped-back waterproof backpacks, you can’t expect the same comfort levels as you would from a fully-featured hiking rucksack. But, the Rapid 26L isn't uncomfortable at all. You get a good amount of padding in the back panel and shoulder straps, and he pack also feels very stable when it's full. There's no sagging in specific areas, so the weight distribution is nice and even.

When it comes to a final verdict, the Sea to Summit Rapid 26L Dry Pack is a high-spec waterproof backpack that outperforms many of its competitors. It’s certainly not a cheap rucksack, but when you consider the brand it’s made by and the materials it’s constructed from, the price isn’t outrageous either. Durability is our big highlight.

The Fogland Waterproof Backpack takes a different approach to many of the other backpacks here.

Where most of them are quite lightweight and almost like a glorified dry bag, the Fogland is chunky, stiff, and utterly watertight. When we say watertight we mean it. Throw the Fogland in a lake, submerge it, it'll keep your contents dry.

It does this by using a TPU-coated 420D nylon material and drysuit-quality zippers to ensure to no water or dust gets in.

Despite the hardcore waterproofing, we found this is quite a user-friendly backpack that's suitable for everyday use, in addition to water sports and outdoor adventures. That said, some of the other options here are better for hiking.

We like that it's a tough backpack too, with that main fabric being highly abrasion and puncture resistant.

YETI’s Panga backpack eventuated when the brand wanted to make a backpack version of its Panga Duffel. So, YETI simply took the TPU-laminated nylon material it called ThickSkin Shell and plied it into a backpack shape.

Like the duffel, the Panga backpack retains a sturdy EVA-moulded base, metal hardware, and crucially, a totally watertight design using a chunky HydroLock zip. More than water resistant, YETI says the Panga backpack is submersible.

Like the Breakwater Supply Fogland Waterproof Backpack, we can’t fault the Panga backpack’s waterproofing. With the zip closed properly, the inside of the bag is airtight and no moisture gets in. Ever. We were impressed with how sturdy the Panga backpack is too. Everything feels like it’s made to outlast the person wearing it and if cared for properly, it certainly feels like something you only buy once.

The flip side of this sturdiness, however, is that it’s a heavy backpack for its size. We were sceptical about the shoulder straps at first, but they ended up pleasantly surprising us with decent comfort levels. But, that said, this is by no means a hiking backpack.

The longest outing we wore the Panga backpack on was 10 miles. Loaded up with about eight kilograms of gear, the shoulder straps were perfectly comfortable, but the flat, non-ventilated back panel is very capable of making your back sweaty. There are removable chest and waist straps, but they didn't make much of a difference for us.

Overall, with good storage solutions on the interior and truly faultless waterproofing, this is a superb pack that will last forever. But, it's definitely not for hiking, and we're still having some trouble getting over the steep price.
