It'll inflate your Therm-a-Rest sleeping pad in seconds without leaving you lightheaded and gasping for breath, and when not in use it doubles as a waterproof dry bag to stash your gear. Mind, blown.

Timesaving – Inflates your pad faster than breath inflation. Easily snaps onto Therm-a-Rest valves.
Versatile – Doubles as a lightweight 20-liter dry sack when it’s time to hit the trail.
