Made with bamboo and rayon, both wood fiber based materials, these gloves protect your hands and fingernails while providing amazing grip, dexterity and tough protection. The ROC grips like iron, feels like bare hands and keeps your hands cooler and drier. With a rayon shell these gloves are lighter, cooler and more absorbent than other cotton gloves. One of the chief complaints people have about wearing gloves is that their hands get hot. The ROC rayon made from bamboo fabric is moisture wicking and breathable, and its natural UV protection makes working outdoors worry free. The nitrile coated palm provides great grip wet or dry, with increased abrasion and puncture resistance. Comfortable form-fitting shells allow extra dexterity for working with small items. Self-fitting knit wrist keeps dirt out. Easy clean ROC is machine washable - just lay flat to dry. Not liquid proof.
