Whether you're posted up by the campfire, enjoying your seventh s'more of the evening, or cruising up one of Castle Rock's famed routes, the Nano Puff provides lightweight warmth. This classic midlayer boasts a tenacious exterior thanks to the recycled polyester shell and lining, which when combined keeps wind out and warmth in, while the fabric is treated to prevent light precipitation from getting the best of your time spent outside.
