28mm Filter Kit

The 28mm threading is universal enough that I've swapped it between three different bottles this week, and the inline design means I can filter straight from my reservoir without extra adapters. Setup took under a minute, and it's already saved me on a trail where the only water source was a questio

The threading is perfectly snug on my 28mm bottles, so there's zero wobble even when I'm hiking fast. Swapping it between my flask and reservoir takes seconds, and the inline install is way simpler than I expected. Water tastes clean with no plastic aftertaste, which is the real win here.

Took this on a three-day backpacking trip and it screwed right onto my 28mm flask with zero leaks, even bouncing around in my pack. Filling from streams was fast and I never had to stop and dig out a separate pump.
