Protects against 99.999999% of bacteria (including E.coli, Salmonella), 99.999% of parasites (including Giardia and Cryptosporidium), 99.999% of microplastics, silt, sand, and cloudiness

Enhanced microfilter performance: the re-engineered membrane and custom backwash accessory means better performance against sand and silt, maintaining great flow over the long haul.

Ultra-compact, the reconfigured filter is tiny but mighty with a super packable kit that doesn’t sacrifice weight or space. Backcountry versatility for trail running, through hiking and limited space adventures!

Extreme durability: 2x thicker, premium materials make it tougher and ultra leak-proof.

Highly versatile means the collapsible squeeze bottle system is designed with every occasion in mind. Use as a bottle, squeeze water through it into cooking containers or other drinkware, use as a straw, remove the filter to use as a storage system, or connect to other Peak Series systems.

The filter membrane density has been optimized for flow rate and the over-cap features and smart seal mouthpiece prevent leakage.
