6L WATER STORAGE: Portable and packable, the Pioneer is built for multiple days on the trail. It features an innovative two piece construction. A removable water storage reservoir and an abrasion resistant outer sleeve. EASY TO FILL & CLEAN: The reservoir’s Slide-Seal top opens wide for quick filing in spigots or streams and closes tight for a leak proof seal. It can be turned inside out for cleaning and drying between trips. WATER FILTER COMPATIBLE: Filter more water in the backcountry via the included 28mm thread adapter, compatible with most 28mm filters (Sawyer Mini and Squeeze). HIGH FLOW CAMP TAP: Our innovative, high flow tap inserts into the Plug N Play connection to create a versatile dispensing solution. Push to dispense water and release to autoseal. Lock open for faster filling or washing up. BEYOND LIFETIME GUARANTEE: If you experience any issue, we’ll repair or replace the item for free. Whatever it takes to keep your adventure going.
