These Gloves provide excellent protection, less weight and greater dexterity. They are seamless and are knit from a yarn that has a central core of stainless steel wire covered in Kevlar (the material used in bullet proof vests). An additional layer of Spectra nylon increases strength, comfort and durability, while decreasing skin chafing. They are not puncture proof, but are highly cut-resistant. They are machine washable. The gloves have a snug, 7.5 cm (3 in) cuff for protection. They are offered in three sizes and are sold in pairs. Wear these gloves over a pair of leather gloves for the utmost protection.
