Platypus Drink Tube Insulator

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).

• Help prevent water from freezing.
• Also helps keep water cool in hot weather.
• Works with most drink tubes and bite valves.
