Our heat resistant stretch knit sleeves have 2-Layers of Dupont's Nomex IIIa™. Nomex IIIa is more expensive and has better heat resistant properties than Kevlar, so don't be fooled by the cheaper Kevlar gloves. Our sleeves protect your arm, back of hand, and palm against accidental contact up to 1,300°F. Keep covered from hand to biceps with these one size fits all, ambidextrous sleeves that are comfortable, breathable, antistatic and machine washable. Sold as: 1 Sleeve
