Both 8L gravity and storage bags are fully leak-proof systems allowing for mobility, and the safe-water storage bag has a custom easy-pour screw-spout for fast flow and a hose attachment for added functionality and versatility. You can even remove the filter from the gravity bag and use as a straw on the go, connect to a water bottle, or use the included plug cap to stop flow and use as a second storage system. Made of high-performance materials for long term durability, you won’t have to worry about punctures or rips during your travels. This gravity water filter system with safe storage has multiple carrying options, while boasting a simple but enhanced filtration system designed to prevent clogging from sand and silt. It’s the only gravity water filter system with added safe storage you’ll need for you and the whole crew for as long as you’re on your adventure. 

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