Designed as part of an integrated system for mountain running, this ultralightweight wind shirt is fast-drying, breathable and constructed with Capilene® Cool Lightweight fabric in the sleeves and hood. Longer sleeves make it possible to cover your hands so you can skip bringing gloves. A slim-fit hood provides extra warmth and protection in lieu of a hat, and a DWR (durable water repellent) finish provides some weather resistance. Packs down into the back neck for easy stowing. Made in a Fair Trade Certified™ factory.
