Developed in collaboration with SealLine, the pump sack is built from ultralight BlockerLite waterproof material with welded seams for genuine dry sack protection of up to 20 litres of gear. On the water or in wet conditions, that means your extra layers and camp clothes stay dry inside the sack right up until you need them for pad inflation. Snapping onto WingLock or TwinLock valves, it inflates a high-volume air pad significantly faster than breath inflation, which is a welcome shortcut at the end of a long day on a canoe route or backcountry trail.

A dual-purpose piece of kit that earns its place in any paddler or backpacker's gear list.
