Chemi-Pro® Unsupported, Heavy-Duty, Cotton Flock-Lined, Neoprene Over Natural Rubber Latex A unique dipping process which combines neoprene over natural rubber latex provides increased protection against a wide range of chemicals. The gloves are 27 mil thick for extra ruggedness and durability, and the 13" length is longer than most standard gloves for added forearm protection. A recessed diamond-embossed pattern provides added grip on wet or dry surfaces, while a cotton flock lining absorbs perspiration and increases worker comfort. Chemi-Pro gloves are an economical, cost-saving substitute for higher-priced, heavy gauge nitrile and neoprene gloves.
