Keep your mountain movements
in a state of Flux

Published by Mountainblog on .

Stay on the move through the cold mountains in this warm and highly breathable jacket. Polartec’s Alpha Direct insulation is the star of Rab’s Alpha Flux multi-season Jacket for women (men’s version also available).

Designed to perform as either a warming midlayer during the winter or protecting outer layer in the warmer seasons, the Alpha Flux provides comfortable temperature regulation and stretchy freedom of movement.

Polartec Alpha Direct evolved from Polartec’s original Alpha material. It’s an ‘active’ ‘naked’ insulation layer that’s windproof, and continuously releases excess body heat before it builds up. Stopping sweat from causing saturation and chills.

Its soft lofted fibres increase the fibre’s breathable performance; speeding up the drying process and reducing the Flux’s overall weight.

The perfect choice of fibre for fast-paced activity in cold climates. The outer of the jacket is made with a lightweight nylon for increased durability and abrasion resistance.

An under-helmet hood and front zip with internal storm flap and chin guard provide additional comfort and protection, while stretch fleece side panels allow more movement. With Polygiene® antibacterial odour control treatment to ensure freshness over multi-day use, Rab describes the Alpha Flux Jacket as “ideal for long climbing days and scrambling.”
