Hydrapak Hydrasleeve 3L

A water reservoir lined like a cooler. This is what the Hydrasleeve cover provides: the water stays at its own temperature instead of taking on the temperature of your back.

Insulation

The cover combines EVA foam with a heat-reflective lining. The foam insulates through conduction, while the reflective material bounces back radiation; both mechanisms complement each other, which is why they are used together.

Result: the system works just as well in low temperatures as in high ones.

Filling

The Slide-Seal top opening has been redesigned and enlarged: it's easy to fill at the tap, and you can fit your hand inside for drying.

The tube

HydraFusion, 914 mm, flexible and insulated. High-flow valve, dust cover, operable with one hand.

Construction

High-quality elastic thermoplastic polyurethane, with polypropylene, EVA, and nylon. The reinforced coating makes it significantly more resistant to physical damage than a bare reservoir.

A nylon handle allows it to be attached or hung up.

Capacity 3,000 ml, weight 308 g.
