For years firefighters, EMS, utility workers and members of the armed forces have endured flame resistant apparel that is bulky, uncomfortable and even dangerous as performance deteriorates over time. The Polartec flame resistant system includes next-to-skin base layer fabrics that wick and dry quickly, mid layers with stretch, lightweight thermal insulation layers and weather protection outer layers, all optimized to work together as a system. Polartec offers durable, lightweight, breathable options that dry quickly and do not inhibit range of motion.
