Rab Ascent Jacket - Women's fit down jacket with detachable hood. The Women's Ascent Jacket has been designed as a Mountain and Hill Walking jacket, but is also ideal for trekking and travel or for daily winter use. The Women's Ascent is a bit longer in the body and has a detachable hood, we also use 330g/12oz of US650 Fill Duck down that means the Ascent is very warm for it's weight but also relatively light and fantastic value. The outer Pertex Endurance fabric is water resistant so ideal for use in snow or and also very durable.
