Waterproof hiking & trekking bags

Essential for peace of mind on any adventure, dry bags protect your gear from rain, moisture and dust wherever you go. Explore our range of dry bags for hiking, from lightweight compression sacks to robust waterproof backpacks.

Why choose a dry bag for hiking?

To keep your backpack organised, opt for dry bags. These bags have multiple uses, such as separating dirty gear, protecting your equipment from water, dust or sand during hikes, treks, water sports and other expeditions. Out in the field, threats go beyond rain: morning dew soaking through fabric, river crossings, muddy trails or condensation under the tent can all leave your sleeping bag, spare clothes or electronics wet. By keeping essentials dry, a dry bag becomes a discreet but crucial ally, from day hikes to multi-day treks.

Reliable protection against water and moisture

How can you tell if a bag will truly keep water out? Two factors matter more than the look of the fabric. The first is the hydrostatic head, measured in millimetres: it indicates the pressure the fabric can withstand before letting moisture through, and a reliable dry bag far exceeds 10,000 mm. The second is construction, with heat-sealed seams rather than stitched ones, forming a continuous barrier where simple stitching would let water seep through needle holes.

The closure system is just as important as the fabric. The roll-top closure, which rolls several times before clipping shut, remains the most reliable and straightforward solution for hiking: when properly closed, it protects against rain, splashes and brief immersion. A waterproof zip, on the other hand, offers quick access to contents, ideal if you open and close your bag frequently. Sea to Summit, a recognised specialist, exemplifies this pursuit of waterproofing without compromising on lightness: discover all Sea to Summit dry bags in our selection.

Durable and robust materials

The reliability of a dry bag starts with its fabric. TPU coatings, PVC or coated nylon, sometimes made from recycled materials, combine abrasion resistance and long-term durability, where thinner fabrics give way at the first scrape against rock. Welded seams, rather than simple stitching, block water from seeping through needle holes, and the most technical models feature a high hydrostatic head, often 10,000 mm or more. This careful construction, found in both Exped-a specialist in dry storage bags in every size-and Sea to Summit, turns a simple accessory into a lasting investment: a good dry bag will serve you for years without letting you down when it matters most.

The different types of dry bags

Not all dry bags serve the same purpose, and the right choice depends as much on your activity as on the volume you need. Before comparing sizes, consider how you'll use them: some are carried alone, others organise the inside of a standard backpack.

• Waterproof backpacks are worn like regular hiking packs and are ideal for full days out, whether in the mountains or by the water, when you need to keep all your gear protected;
• Compression sacks and dry pouches organise the inside of your pack: they separate wet clothes, protect a sleeping bag from ambient moisture or keep a phone safe from sudden showers. For this type of organisation, the Light Drypack range from Deuter or our compression sacks are the perfect addition.

Volume is just as important as waterproofing. For a day trip, 15 to 30 litres is enough; a self-sufficient weekend calls for 40 to 60 litres, while multi-day expeditions require 80 litres or more. One often-overlooked detail: with a roll-top closure, the actual capacity is reduced once the bag is closed. If you're unsure between two sizes, it's best to choose the larger one.

How to use and care for your dry bag

A well-maintained dry bag will last for years, provided you follow a few simple steps. The first rule is moderation: an overfilled bag won't close properly and loses the waterproofing that makes it valuable. In hot weather, condensation is more likely inside; placing an absorbent sheet of paper at the bottom will capture any residual moisture. After use at sea or in salt water, rinse with fresh water to preserve coatings and welds, which wear out faster with salt. Always store your bag open and completely dry, as closing it damp encourages mould and weakens seams. Before heading out in tough conditions, a quick test will reassure you: place a tissue inside, close the bag and submerge it for a few minutes; if it comes out dry, you're good to go.

FAQ: Dry bags for hiking

Are dry bags truly waterproof?

It depends on their construction. A bag that is only water-repellent or stitched will resist splashes and light rain, but will let water in if submerged: this is water resistance rather than full waterproofing. For reliable protection even in heavy rain or brief immersion, choose a model with a roll-top closure and heat-sealed seams, with a high hydrostatic head (10,000 mm or more).

How do you choose a dry bag for different weather conditions?

For hiking in moderate rain, a water-resistant bag with sealed seams is enough in most situations. When you're near water, crossing rivers, doing water sports, or facing heavy weather, opt for a fully waterproof model with a roll-top closure and heat-sealed seams, and a high hydrostatic head.

Can you use a dry bag for other outdoor activities?

Yes, and that's one of its main advantages. Beyond hiking, a dry bag is useful for trekking, kayaking, paddleboarding, canoeing, fishing or trips to the beach. Just match the volume and waterproof rating to your activity so it stays relevant all year round.

What accessories go with a dry bag?

For complete protection, pair your dry bag with waterproof pouches for your phone or documents, a padded cover for electronics, and compression sacks to optimise storage inside your bag.
