Comet Mountain is another Beaverhead Peak that rises proud from the valley floor. This hydro-ply fabric is a natural-technical mash-up. Perfect as a first layer in cooler conditions or worn solo as an alternative sweatshirt. Combining a pure Helle Rambouillet outer and an ultra-thin microfiber inner layer. All the performance of fast-wicking poly and absorbent wool. The hydro-ply fabric wicks moisture off your skin into the absorbent wool second layer keeping you amazingly comfortable and warm. A favorite fabric of professional Outdoorsmen, this hydro-ply combo is very durable while remaining soft to the touch.
