Description

Three millimetres of neoprene carrying a 5mm suit's thermal construction is an unusual combination, and it is the whole argument for this suit: warmth near the thicker version with far better flexibility and less buoyancy, meaning less lead and less shoulder fatigue over a long finning swim, in a suit that folds smaller for a live-aboard bag. The hexagonal thermal lining across the chest and back is the same one the 5mm uses, pinning a warm layer against the core instead of letting water wash through, over stretch neoprene throughout. Smoothskin closes the wrists and ankles, the back zip hides behind a lined flap, textured shoulder panels shed surface water and reflective seam piping runs down the arms and legs. Fourth Element rate it from 23 degrees Celsius upward, and layers underneath take it cooler. Sizing spans X Small through 3X Large with Short lengths, black with white seam accents. It suits a diver working tropical or warm water.
