To make the most of the waves, the Tango 4:3, made from 100% Yamamoto neoprene, offers the highest level of elasticity and thermal comfort in its thickness category. Its "front zip" construction with 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 4mm neoprene and Thermal X inner lining provides better thermal comfort in the torso, along with internally sealed seams.
