This flexible fleece vest is developed for mountaineering activities and is an excellent choice for general outdoor endeavors when the temperature lowers. It's made in premium Polartec® Thermal Pro® because of its superb warmth-to-weight ratio. The Polartec® Thermal Pro® consists of 100% recycled polyester and has a weight of 295 g/m2. It offers unique knit techniques to create air pockets that trap air and retain body heat, providing outstanding warmth without weight. Not only are they very comfortable, but these fabrics offer excellent breathability, dry quickly, and are very durable and pill-resistant. Key features include two hand warming pockets, a neat chest pocket, and a warm and weather protective collar. The vest has a technical fit with a slightly longer back for extra protection.
