Customer Reviews (4.8 / 5 · 5 reviews)

James ★★★★★

The one-ounce weight is almost nothing in my pack, and I love that it doubles as a dry bag to keep my mattress clean. It inflated my pad in under a minute with zero moisture from my breath.

Scarlett M. ★★★★★

Inflating my mattress with this took way less effort than huffing into the valve for ten minutes. The one-ounce weight means I don't think twice about stuffing it in my pack, and it keeps the mattress dry when I roll it up damp.

Ella P. ★★★★★

This little bag does double duty more cleverly than most gear I own. It's barely there at one ounce, but rolling it up inflates my mattress fast without me getting dizzy, and my dry clothes stayed dry after a rainy night. The valve seals tight too—no leaks on the trail.
