Expertex? Hybrid Primary Protector is an arc rated, cut resistant and flame resistant protector that is built to ASTM F3258. This new protector standard allows for the use of synthetic materials so long as those materials adhere to certain safety criteria. These synthetic materials are able to enhance the overall safety of the glove while maintaining a lighter weight feel and flexibility. The innovative protector is Cut Level A5, Puncture Level 5 (Palm) & 3 (Top) and Arc Rated to 29 cal/cm2. The palm is made of high quality water resistant cow grain leather to ensure lasting durability and grip. The top of hand and cuff are made with proprietary FR Woven fabric. The entire interior of the glove is lined with Kevlar? for added cut, flame and arc resistance. The protector also features FR reflective material for increased visibility along with an FR Strap and Fastener.
