Essential for peace of mind on any adventure, dry bags keep your gear safe 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 kit 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 soaked. By isolating what must stay dry, a dry bag becomes a discreet but crucial ally, from day hikes to multi-day treks.
Reliable protection from water and moisture
How can you tell if a bag will really keep water out? Two factors matter more than the look of the fabric. The first is the hydrostatic head, measured in millimetres: this shows how much pressure the fabric can withstand before letting moisture through, and a reliable dry bag will far exceed 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 need to open and close your bag frequently. Sea to Summit, a recognised specialist, is a great example of uncompromising waterproofing with minimal weight: 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 can fail at the first snag. Welded seams, rather than simple stitching, prevent leaks 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 bags of all sizes-and Sea to Summit, turns a simple accessory into a long-term investment: a good dry bag will serve you for years without letting you down.
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 shapes, keep usage in mind: some are carried alone, others are designed to organise the inside of a standard backpack.
- Waterproof backpacks are worn like a regular hiking pack and are ideal for full days out, whether in the mountains or by the water, when all your gear needs to stay protected;
- Compression dry bags and pouches organise the inside of your pack: they separate wet clothes, keep a sleeping bag dry or protect a phone from a sudden downpour. For this kind of organisation, the Light Drypack range from Deuter or our compression bags 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 in doubt 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 soak up 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 give you peace of mind: 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 really waterproof?
It depends on the construction. A bag that's 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 cases. If you're near water, crossing rivers, doing water sports, or facing heavy weather, go 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 perfect for trekking, kayaking, paddleboarding, canoeing, fishing or trips to the beach. Just match the volume and waterproof rating to your activity so it stays useful 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 bags to optimise space inside your pack.
