U.S. Cavalry is introducing the new line of flame resistant clothing for military, tactical, or outdoor adventurer. XGO, the newest brand from Longworth Industries features clothing with Acclimate®F/R technology that helps protect the wearer against flash burn injuries in a combat situation. XGO flame resistant garments increase the protection degree for a short duration by staying intact when exposed to short duration flame. This protection stems from the modacrylic fiber in the fabric which, when ignited, releases a small amount of inert gas. This gas intercepts oxygen, depriving the flame of it source of energy. Thus, the fire is extinguished. The flame resistance cannot be washed out of the fabric. Another performance advantage is the addition of Scent Prevent® in the construction of the flame resistant garments. The XGO Flame Resistant clothing with anti-microbial properties is highly breathable, effectively wicking away moisture and perspiration from the body. Especially designed with soldiers and tactical operators in mind, the new line up of short and long sleeve T-shirts, pants with fly, boxers, and a balaclava all feature a flat clean seam construction which eliminates chaffing from pack straps or body armor.
