Manual Inflation

Bigger does not mean faster. An inflation sack that's too big is just more material to wrestle. Our slightly oversized UL Inflation Sack is optimized for the fastest inflation time. It's quick and easy to use, just couple the inflation sack to the mattress valve and push air through.

Mattress Storage

The UL Inflation Sack doubles as watertight storage for your mattress. Twist, stuff, and cinch it shut!
