If you're handling ovens, barbecues, grills and other similar hot surfaces, count on the Tramontina Churrasco gloves. Made of aramid and silicone, the gloves have a polyester interior which makes handling much more comfortable and versatile in comparison to traditional oven mitts. The design of the Tramontina gloves is highly insulated, however it's recommended that contact with the hot metals is brief. Prolonged, extended contact with the hot metals can damage the material over time and cause burns. Do not use it in direct flame.
