Sleeves feature a five-layer fabric compacted into 2.7mil. Laminating a high-energy polymer (EVOH) with a low-energy polymer (PE) creates a fabric impervious to at least 90% of all organic chemicals for four hours at 35°C (95°F). Each layer acts as a barrier against various epoxies and industrial chemicals. Can be used with Silver Shield®/4H® gloves and/or apron. Sleeves provide added protection for the upper arms and shoulders. Elastic bands at the shoulder and wrist ensure a snug fit. One size fits all.
