PLATYPUS - BITE VALVE & TUBE INSULATOR KIT

Fend off frozen drink tubes and help keep liquids cool in hot weather with the Drink Tube Insulator.
• The new design offers a completely covered bite valve (to keep it clean and protect it from freezing quickly), a reverse coil polyurethane-coated zipper (to prevent ice/snow build up), a large zipper pull (to easily open with one hand�even with gloves on), and a hook and loop closure shoulder strap attachment (to secure to a pack).
• Works with all Platypus® drink tubes and bite valves.
