It's the simple, lightweight, and compactible option for back-country camping and backpacking. The optimized filtration cartridge delivers a high flow rate and effectively removes sand and silt without clogging. Built with premium materials, the water storage bag is tough enough to endure rugged use—just like the rest of your gear. Designed for long-term durability, so you'll never have to buy another.

This ultra-versatile system is fully leak-proof. Use it as a water storage system while on the move, as a straw filter by itself, or pair it with a standard water bottle. With enhanced microfilter performance and a custom backwash accessory, you get better protection against sand and silt—while maintaining strong flow rate over time.
