Mares Dual 5mm Wetsuit Long John

The Dive360 Take

The Dual long john is the foundation of Mares’ traditional two-piece scuba setup. Its sleeveless, full-length design covers the torso and legs, while the front zip makes getting ready more straightforward than wrestling into a pull-on suit.

The 5mm neoprene provides insulation, and Ultrastretch panels give you some extra room to move. Pair it with the matching Dual jacket and the overlapping neoprene adds another layer around your core — useful when warmth matters as much as getting your arms comfortably into position.

Glideskin ankle seals help limit water movement, while reinforced knees take some of the wear from gearing up and moving around dive sites. Check your body measurements against the guide below, particularly if you’re matching it to a jacket you already own.
