The Airloks are waterproof stuff sacks made from tough and lightweight rip-stop nylon to keep your kit dry inside a pack.

Use Airlok dry bags inside your backpack as a handy way of storing your valuables, spare layers or even your toilet roll! The taped seams and roll-top closure means your items can be kept dry and to hand in your backpack.

A different colour for each size makes it easier to distinguish between sizes and there’s plenty of different sizes to choose from. 45 litres is a useful size if you prefer a full rucksack liner rather than lots of smaller dry bags.
