Cascade Designs Blockerlite Pump Sack

The Therm-a-Rest BlockerLite Pump Sack is a versatile packing option for going on an adventure. Featuring 20L of space, pack up some clothing or other necessities and roll the top at least 3 times for waterproof protection. When you reach camp and it's time to inflate your pad, just empty this sack and hook it to an air pad featuring the WingLock or TwinLock valve. It'll save your lungs and help the pad inflate fast so you can get to cooking, sitting fireside and eventually sleeping.
