Sac étanche à compression ultraléger Evac pour sac à dos et sacoche vélo

Soft gear takes up whatever room you give it. This compression dry bag takes some of that room back, squeezing clothing and sleeping kit down while keeping it dry inside a backpack or bike bag.

There's no purge valve to fuss with. An eVac® fabric base lets air pass out but blocks water, which keeps the design light and simple. The main body is bluesign-approved Ultra-Sil 30D Cordura® nylon with a C0 non-PFC DWR, and the base carries a C0 non-PFC DWR too. A hypalon non-wicking roll-top closure shuts water out, secured by the patented Field Repair Buckle.

Four ultralight straps do the compressing: two ladderlock and two easy-access side-release buckles, sized generously so you can fill the bag right up. Reinforced stitching sits at every stress point. Keep it for internal packing — it isn't built for paddle sports or for mounting externally on a bikepacking rig.
