The Mares Explorer Sport 50 5mm Long John is a 5mm neoprene wetsuit jacket – the upper half of a two-piece diving setup or a standalone layer for added warmth on cooler dives. The front or side zip makes it quick to pull on, and the flexible neoprene construction allows full arm and torso movement. A smart layering choice for the variable conditions at Tioman’s cooler early dives.
