Essentially killing the tedious task of pumping drinking water through a filter forever, the MSR Thru-Link Inline Filter easily attaches to your hydration reservoir, giving you a constant supply of clean drinking water when you're on the go. Best of all, the Thru-Link attaches to any hydration reservoir on the market, and with its two-stage filtration system, it removes bad tastes, odors, microplastics, pathogens, and particulates. MSR has a long history of developing innovative mountain equipment, and with the Thru-Link, we're happy to report that it doesn't appear they're about to slow down any time soon.
