For making the most of the waves, the Tango 4:3, made with 100% Yamamoto neoprene, offers the highest level of elasticity and thermal insulation of its thickness category. Its 'front zip' construction with a YKK zipper creates the best possible seal in the neck without sacrificing freedom of movement in the shoulders. Yamamoto 40 neoprene is also incorporated into the shoulders and back for greater paddling mobility. A combination of Yamamoto 4 mm neoprene and Thermal X inner lining provides better thermal insulation in the torso, along with internally sealed seams.
