Superb warmth to weight ratio. Fabric resists rock abrasion and other rough handling.

You don't have to mountain climb backpack or hike in the deepest reaches of the most remote backcountry to justify the wearing this roasty-toasty and lightweight pullover. The soft velour face of the Polartec® Thermal Pro® Nailhead feels comfortable and delivers an amazing warmth-to-weight ratio no matter what you do in cool weather. The relaxed loose fit design works well with an assortment of layers and help trap and hold pockets of warm air against your arms and torso.
