Mares wetsuits, both men’s and She Dives, are grouped in three main categories: Extreme, Elite, and Prime. Suits in the Extreme family are designed to maximize thermal protection for dives in very cold water (2ndSkin, Antarctica, Isotherm). Suits in the Elite family are characterized by the exclusive use of ultrastretch neoprene (Flexa models). Suits in the Prime family are more traditional suits, either as 3 or 5mm steamers, or as farmer john and separate vest (Pioneer, Dual, Reef).
