Stretchy. Breathable. Waterproof. Choose Three.

Forget everything you think you know - the Kinetic Alpine will change the way you dress in the mountains.

Fully waterproof, highly breathable and stretchy, this is a radical re-approach to protective yet comfortable clothing systems. Perfectly combining the supple, flexible nature of a softshell with the protection and durability of a hardshell, gear using Proflex fabric contours to your body shape. Wicking away any sweat generated on steep ground, it's easy to forget you are wearing waterproofs until the showers roll in. At this point you no longer have to pause and reach into your pack - simply push on.

How does it work?

A breakthrough in technology, the inspiration for the Kinetic Alpine came directly from the fabric– Rab’s own Proflex.

Constructed from a highly flexible hydrophilic membrane positioned between two high gauge, knitted layers, Proflex’s unique knitted structure has been developed by Rab to optimise performance.

Working simultaneously the inner quickly wicks sweat and moisture, while the outer protects you from the elements.
