The glove provides heat and flame-resistant so the glove will not burn or melt. The duck material in the cuff offers a more economical choice when compared to a full kevlar heat glove. The loop out structure dissipates the heat, while the wool lining provides the added heat protection to protect against temperatures up to 700 deg F.
