The MSR Hydration Kit is an easy-to-use kit that converts MSR Dromedary and DromLite bags into hands-free hydration systems. The MSR Hydration Kit includes a leakproof MSR Bite Valve and shutoff valve. A 42-inch (107-cm), taste-free polyethylene-lined drinking tube resists freezing for when you want to take your bag into colder climates. A custom hydration cap with 360-degree swivel elbow allows you to take a sip from your bag from wherever your position. With the MSR Dromedary and DromLite bags, you have some of the best water carriers around. Maximize their potential with the MSR Hydration Kit.
