The Source WXP Storm Valve 3L is a high-performance tactical hydration bladder designed for long missions and outdoor use. Built from a 3-layer co-extruded polyethylene film, it preserves water taste and offers exceptional durability. The Storm high-flow push-pull valve rotates 360° for perfect mouth alignment and enables a shorter drinking tube to reduce chest bounce and snag risk. Widepac sliding seal provides wide access for easy filling, ice insertion, cleaning and drying. The glass-like film and Grunge-Guard antibacterial technology inhibit biofilm formation; the fabric-sheathed hose insulates the fluid and blocks UV light.
