Powerful filtration that stays steady on the move

The optimized cartridge delivers a high flow while filtering out common backcountry contaminants, including sand, silt, and cloudiness. You’ll notice clearer water and a smoother taste, especially after filtering streams or reservoir water during long hikes or camping sessions. The system’s protection is described in performance terms, offering a high level of filtration across several categories without making medical claims.

• 99.999999% protection against bacteria (E. coli, Salmonella) and parasites (Giardia, Cryptosporidium), plus microplastics
• Effective removal of silt, sand, and cloudiness for clearer, more palatable water

Durable, versatile, and ready for the backcountry

Crafted from premium materials, the Peak Series is built for rugged outdoor use with an ultra-leak-proof design. Its versatility shines in multiple setups: use it as a gravity filter, as a large squeeze bottle, as a direct straw, or paired with your own water bottle. The result is a flexible filtration system that adapts to your adventure, whether you’re filtering on the move or staying hydrated at camp.

• Ultra-durable construction designed to withstand rough handling
• Fully leak-proof for storage and transport in backpacks or gear beleaguering trips
