Details Rab Alpha Flux Women's Jacket The Rab Alpha Flux Jacket is a highly breathable, lightly insulated layer which uses Polartec® Alpha™ Direct technology and a stretch fleece for ‘on the move’ multi-season use. The Alpha Flux Jacket uses a new, soft woven outer fabric which has a high level of permeability, together with a light stretch fleece in strategic areas to let you move freely and to reduce bulk. The result is the perfect insulation piece, created with Polartec® Alpha™ “Direct” 90 insulation; ideal for changeable conditions from early Spring right through to late Autumn. As an outer layer the Alpha Flux Jacket keeps your body temperature in balance when you need a degree of warmth while working hard in the mountains. It also serves impeccably as a warmer, fast drying mid-layer in windier, cooler conditions.
