Carbon Knight Hood has a flame retardant tri blend material composition that includes kevlar for a superior strength and durability. The thermal knit construction makes the material feel heavy but it is very light weight at 6.7 oz per square yard. The thermal knit also allows air to be trapped in the material to keep the user cool in hot environments and warm in cold environments. The Carbon Knight material wicks moisture away from the skin and had odor absorbing qualities. With a TPP rating of 37.4, this hood exceeds NFPA requirements.
