HydraPak's unique and versatile 28mm InLine Filter threads directly onto many popular 28mm opening bottles and works in-line with their reservoirs as well. It can be used with their 1L Stow bottle, our Seeker Hydration Bundle, and our hydration-bundled Sandur, Choss, and Hopper bags. This versatile connectivity makes their filter a great backcountry water treatment solution whether you are squeezing your water from a Stow into another bottle, gravity filtering out of a Seeker, or filtering as you drink from a HydraPak reservoir.
