The Brass Knuckle SmartShell heavy duty protective glove, No. BKCR4599, offers heavy duty cut resistance, light oil and moisture resistance, non-tacky slip resistance, and shock-absorbing impact protection. The glove also delivers ANSI level 4 cut resistance and is breathable and durable. On the palm and fingers, the BKCR4599 offers three layers of protection. The liner is an ultra-high-performance polyethylene (HPPE) and spandex composite that delivers strong cut resistance without bulk. Bonded to that first layer is a gray polyurethane (PU) fabric topped with a grippy nitrile surface—a barrier to light oil or other light liquid penetration. In critical areas of the palm, padding provides impact resistance. Also, the back of the hand is loaded with sonically welded thermoplastic rubber (TPR) padding that easily counters workplace pounding and abrasion.
