These Flight gloves are modeled to US military specifications. They are constructed of a knit blend using Nomex® fibers and are sewn with Nomex® thread. They feature a palm made of premium goatskin leather noted for its long-lasting durability and abrasion resistance. This high-performance construction is flexible even after heat exposure. WARNING: Flame-resistant fabric is not fireproof. Flame-resistance is an inherent property of the meta-aramid material used on the back of the hand & thumb. Use common sense and exercise caution when encountering potential hazards.
