For standing about for long periods of time, warm layers are essential. Rab, the climbing experts have constructed a jacket that works well in variable conditions. On cold, dry days the Alpha can be worn as an outer or as a mid layer when the weather turns nasty. Made using Pertex Alpha in the lining, this fabric is compressible with a core of lofted knit fibres which increases air exchange and speeds up dry times. Breathable, wicking with a water repellent outer layer, coupled with a Pertex Microlight outer for wind resistance and durability, you have a great combo. Comes with a under helmet hood, fleece stretch cuffs and three pockets.
