It is made from a lightweight 70D waterproof, durable Nylon fabric so you can squash them into spots heavy-duty dry bags won't go. The interior polyurethane coating is coloured white to improve visibility and make it easy to find small items in poor light. Available in five colours to optimise colour-coded organisation, they use the same non-wicking roll-top closure as our other dry sacks for a reliable watertight seal. Featuring a D-ring at the field repairable buckle point for easy attachment, they're ideal for backpacking, cycle touring, travel, ski touring and more.
