Drink Tube Insulator

The Drink Tube Insulator, by Platypus, is an insulating sleeve designed to prevent water from freezing in the tube in cold weather or from getting too warm in hot weather.

Redesigned, it offers complete protection for the bite valve (to keep it clean and protect it from freezing), a reverse coil zipper with polyurethane coating (to prevent ice or snow build-up), a large pull tab (to open it easily with one hand — even without removing gloves) and a hook-and-loop attachment system (to attach it to the shoulder strap of your pack).

• Compatible with all Platypus® tubes and bite valves.
