There are two filters available from HydraPak: the 42mm filter cap and a 28mm filter kit. The 42mm Filter Cap ($35) is compatible with all HydraPak 42mm opening products, including running flasks, Seekers, and Flux bottles. The cap is equipped with a high-flow nozzle and dust cover that opens and closes with one hand while preventing contact with dirty hands. Users can drink directly from the nozzle or squeeze filtered water into another vessel. It weighs just 57 grams (2oz).

The 28mm filter kit ($40) threads directly onto bottles and flasks or connects to Plug-N-Play systems used on reservoirs and and water storage containers. The 28mm Filter is an ideal backcountry water treatment solution whether you’re gravity filtering your water out of a water storage bag or filtering as you drink from a Stow bottle or HydraPak reservoir.

All three include their inline filters, while the largest Seeker+ reservoir also includes a flexible camp tap, their plug ‘n’ play cap, and a backflush adapter—find more on that below.
