Steven U. ★★★★★

Filled it with tap water on a three-day trip and there was zero plastic aftertaste, which honestly surprised me. The minimalist design means there's nothing extra to break or clean, and it slid into my pack like it wasn't even there.

Andrew U. ★★★★★

The whole thing rolls down to almost nothing in my pack, which is exactly what I wanted for day hikes. Water tastes clean with zero plastic aftertaste, and the bite valve flows well without leaking in my bag.

Harper ★★★★★

I’ve used it on three long trail runs now and completely forgot it was in my pack until I needed a sip, which is exactly what I want. The water has zero plasticky aftertaste, even on a hot day when it sat in the sun for hours. Simple, light, and it just works.
