Mechanix sleeves offer arm and wrist protection from excessive heat, lacerations, and abrasions. All sleeves are machine washable so no matter the task, you can re-use them again and again. Sleeve design has built-in thumb holes for a secure fit; the elastic fabric ensures they remain in place. Our heat-resistant sleeves are Kevlar(R) so they continue to protect even after laundering while resisting oils and fluids, and cut protection. Higher level cut-resistant sleeves incorporate tungsten in the fabric for increased protection and textured for anti-slip grip when carrying or working with metals, construction materials, and in manufacturing.
