Keep drinking when it gets cold
A frozen drink tube is one of the quickest ways to ruin a cold-weather outing. The Platypus Bite Valve and Drink Tube Insulator wraps your hydration line in an insulated sleeve that slows the water inside from freezing, so you can keep sipping when the temperature drops and your unprotected tube would have iced up solid.
A cleaner, protected bite valve
The moulded cover fully encloses the bite valve, shielding it from the dirt, grit and mud that inevitably find their way onto exposed valves in the field. It also guards against accidental spills, so your valve stays cleaner and more hygienic between drinks.
Works in the heat too
Insulation cuts both ways. As well as fending off the cold, the sleeve helps keep your water cooler for longer on hot days, making a refreshing mouthful more likely deep into a long patrol, hike or ride.
Easy fit, barely any weight
Designed to fit all Platypus drink tubes and Hyper Flow bite valves, it secures neatly along your pack strap with a hook-and-loop attachment and weighs only around 43g. It is a small, sensible upgrade that protects your hydration system in every season.
