Heavyweight Flame Retardant Thermal Pants - FR Phase 4

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 comfortable, dry and odor-free. Utilizing Clean Seam® flat-seaming to provide a comfortable seam next-to-skin helps reduce the risk of friction and irritation.
