Joshua ★★★★★

Pumped 2.5 liters through it on a muddy creek this morning and the flow rate barely slowed down. The whole thing fits in my hip pocket, which is way more than I can say for the old pump I used to carry.

Andrew Z. ★★★★★

I've been dragging this thing up switchbacks for a week and barely notice it in my pack—the compact size is a huge win. Set it up next to a creek and got clean water flowing in no time, which made the whole trip feel less like a chore.

Ella R. ★★★★★

The pump action is so smooth it feels like it’s barely working, and the whole thing slips into a side pocket without weighing down my pack. Filtered two liters in under a minute on a hot climb, and the water came out clear and cold. Definitely my new go-to for solo trips.
