The Polartec brand is focused on keeping people warm while minimizing environmental impact. Their latest advancement in apparel construction is a fabric technology called Power Air, a 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 outerwear. Available now in a whole range of men’s and women’s jackets & insulators from various brands.
