Technical and versatile pants made from the incredibly soft Polartec Power Air fabric. Comfortable and relaxed fit. Elasticated waist and handy pockets to store your essentials. Polartec® Power Air™ is a new revolutionary knit construction that encapsulates air to retain warmth and reduce microfiber shedding. The result is a performance fabric with advanced thermal efficiency that sheds up to 5x less than other premium mid-layer fabrics. And while all fabrics will shed fibers over time, Polartec® Power Air™ is a step forward in reducing the environmental impact of what we make and wear.
