Built tough so that it can be thrown around outside the pack, the insulated HydraSleeve™ keeps your water cold. The 3L Elite™ reservoir has a soft grab tab for fast loading and unloading and includes an insulated HydraFusion drink tube with high-flow Comet valve and dust cover. Four last point make it easy to secure to any gear rig and the roll top closure creates a handle for carrying or hanging a gravity feed.
