The Amazing Glove Deluxe dramatically extends the time your hands can handle hot objects. The glove withstands extreme dry heat up to 480 degrees. The outer layer of the glove does not catch fire and does not melt. The heavy duty exterior layer of the Amazing Glove forms an intense thermal isolation barrier. This slows the temperature increase in the ultra-soft double-knit cotton interior of the glove. Glove is lightweight and machine washable. Not waterproof.
