Our FR Primo collection delivers on-the-job protection using premium, inherently flame-resistant materials. Ultra-soft and ultra-durable, this fleece is 3X more wind-resistant than cotton fleece of the same weight. Built-in stretch and must-have details, like a hidden phone sleeve, make it an instant favorite.
