Peak Series 8L + 8L Gravity System (Dark Grey)

The LifeStraw Peak Series 8L + 8L Gravity System is a high-capacity filtration and safe water storage solution built for group use, base camps, and extended outdoor trips. Combining an 8L dirty water bag with an 8L clean water reservoir, it allows you to collect, filter, and store water in one efficient, easy-to-use system.

Designed for simplicity, the gravity-fed setup requires no pumping—just fill, hang, and let the system filter. The enhanced membrane microfilter is engineered to maintain strong flow while helping prevent clogging from sand and silt, ensuring reliable performance in real-world conditions.

Both the filtration bag and storage reservoir are fully leakproof, allowing you to safely transport water as well as store it. The clean water bag features a custom fast-flow screw spout for easy pouring, along with the option to attach a hose for added flexibility around camp.

This system is built for versatility. The filter can be removed and used as a straw for direct drinking, connected to a water bottle, or paired with the included plug cap to create a second storage solution when needed.

Constructed from premium, puncture-resistant materials, it’s designed to withstand repeated use in demanding environments without worrying about rips or damage.
