Conforms to EN 388 Complex Design. PVC dipped cotton liner. Waterproof and supple manufactured using a patented process that involves dipping a fine knit. Their performance and longevity are improved by a special hydrocarbon treatment. The cotton liner is both soft and comfortable. PVC, the material that is known to offer the greatest resistance to oils and chemicals (hydrochloric acid, caustic soda and kerosene in particular), does not cause allergies. It provides maximum resistance to abrasion (level 4), which is reinforced by a rough finish on the hand that allows objects to be gripped securely.
