The Alpha Direct Jacket is an incredibly versatile layering piece able to be worn as either an outer or mid-layer depending on conditions.

Rab say: "During an alpine adventure every kind of condition can be experienced, from a warm walk or ski to the base of a route to shivering it out on a freezing belay. In these varied conditions the Alpha Direct balances moisture control and comfort when on the move with warmth and protection from the elements when static."
