An evolution of the Castoro 2 model, with improvements to some important technical features and aesthetically restyled. It comes in the men’s and ladies’ versions, and is a modular suit, made up of one-piece, jacket and hood, which can all be purchased separately. The long-sleeved one-piece is made from 5 mm neoprene, with a very strong YKK rear zip, complete with the Aquastop system under-zip. The Aquastop system, which consists of smooth 1.55 mm neoprene seals, coated in Metallite has been adopted for the wrist and ankle areas, while the shoulder and knee zone is protected from wear and tear by large inserts made from Power Tex. The legs are preformed to guarantee great kicking ease. The short-sleeved jacket with incorporated hood is made from 3.5mm neoprene and zips up to the chin. To limit water seepage, it has a watertight seal around the face.
