Platypus - Tube insulator

Platypus - Tube isulator, insulating sheath

The Platypus Insulation Kit helps you keep liquids cool in hot weather and prevent them from freezing in cold weather.

The new design offers a fully covered bite valve (to keep it clean and protect it from freezing quickly), a polyurethane coated reverse coil zipper (to prevent ice/snow buildup), a large zipper pull (to open easily with one hand —even with gloves) and a shoulder strap with hook-and-loop closure (to attach to a backpack).

Works with all Platypus ® drink tubes and bite valves.
