Montbell designed our DURAGRIP fabric especially for gloves. We started with a durable Ballispan ripstop nylon that is woven with 27% Kevlar threads. Then, we coated the outside of the fabric with silicon and put a polyurethane film on the inside. Exceptionally resistant to abrasion and tears, DURAGRIP provides a great grip. Because of the silicon treatment, snow and water slide right off, and the gloves stay supple even in the cold.
