Dry Bags, Storage and Containers
One wet river crossing or one afternoon of rain is all it takes to soak a sleeping bag, a down jacket or a phone. A dry bag is the cheapest insurance you can put in a pack, and it's the difference between a damp night and a miserable one.
Our range covers everything from ultralight roll-tops to hard-sided containers. The Sea to Summit Ultra-Sil dry bag is the go-to for hikers counting grams, available from 3L up to 35L and packing down to almost nothing when empty. It's also sold as a four-piece set, which is the easiest way to sort a pack into sleep gear, clothing, food and electronics without buying sizes one at a time. If you want to see what's inside without unrolling, the Lightweight Dry Bag View has a translucent panel; if you're on the water, the Big River range steps up to heavier fabric and welded seams built for rafting, kayaking and boat decks.
Every Sea to Summit dry bag in the collection uses a roll-top closure, so the seal is only as good as the technique — three firm rolls before you clip, and leave a little air inside if you want it to float. Alongside Sea to Summit you'll find Exped Drybag Ultra and Versa sets, the Exped Schnozzel pump bag for inflating sleeping mats without breath moisture, Mont X-Force compression sacks for squeezing down bulk, and Osprey pack liners for waterproofing a whole pack at once.
For anything that leaks the other way, we stock Nalgene HDPE and polypropylene containers in round, square and rectangular shapes from 30ml to 1L — good for decanting fuel, sunscreen, spices and toiletries — plus TSA-compliant travel kits, Exped and Sea to Summit first aid dry bags in high-vis colours, packing cubes, and waterproof map and phone cases.
Not sure what size you need? As a rough guide, 8L suits a sleeping bag for one person, 13L to 20L handles clothing for a multi-day trip, and 3L to 5L is plenty for electronics, a first aid kit or a day's food. Our team hikes and paddles with this gear, so if you're weighing up ultralight against hard-wearing, call the shop or send us a message.
