Our Thermastat™ Gloves are made with FDA accepted materials and can be used in food processing applications. Thermastat is a DuPont™ hollow-core hydrophobic polyester fiber that is an excellent insulator. Not only does this fabric hold in warmer air, but also helps wick away perspiration. Can be worn as a liner underneath other types of gloves to provide insulation or worn alone to provide protection. Great for use refrigerated environments. One size fits all.
