Yamamoto #40 in the arms and shoulders provides exceptional flexibility, reducing paddling fatigue. The custom-made jersey brings a silky feel alongside amazing stretch. Triple-glued seams and internal taping fortify critical areas, while a rubberized liquid seal minimizes leakage without sacrificing upper body freedom.
