Our FR Phase 4 is constructed using our patented heavyweight FR blend of Modacrylic & FR Rayon. This is our warmest FR option. Available in many styles and accessories. Great alone or as a top layer piece for extreme warmth. Great next-to-skin feel and a full generous cut for comfort. Our FR is inherent and built-in at the yarn level, meaning it won't wash out and provide no melt/no drip protection for the life of the garment. Acclimate® Dry moisture management and Ag47® anti-microbial/anti-odor will keep your face protected, comfortable and odor-free. Utilizing Clean Seam® flat-seaming to provide a comfortable seam next-to-skin helps reduce the risk of friction and irritation. Lightweight and perfect as a standalone piece or as a layering compliment. Perfect under Nomex to add some breathability and wicking
