Constructed to be truly non-flammable, the Ultimate Baselayer keeps comfortable heat in during winter conditions and extreme heat out when facing dangerous conditions. It will not burn, melt or ignite – even after intense exposure to flame and heat. It’s also highly resistant to molten metal splash, flammable liquids and hot chemicals, and provides excellent protection from arc flash hazards. Made from an 8-ounce/yd2 knit fabric, it’s flexible and comfortable next to skin.
