Ursuit Tørdragt Heavy Light FZ ManTrilaminate diving suit for all users from beginners to professionals Ursuit Heavy Light is a long term favourite for several different purposes. The very lightweight yet resistant trilaminate material provides excellent performance for both entry level diver and a hardened veteran. The revised cut of the sleeves and shoulders enable excellent mobility. The crotch seam is renewed to prevent wear and tear and to provide even better abrasion resistance.
