Reliable sources of 850 padded down-using Coreft synthetic materials in areas prone to moisture-provide superior warmth. The outer layer is made of recycled 15D Arato nylon and dope dyed yarn, making it light and durable. The insulated StormHood hood enhances warmth, and the streamlined ergonomic fit makes it easy to overlap.
