Abstract: An improved watersuit having a stabilization belt, elastic stretch sections and a wetsuit arm positioning system. The watersuit stabilization belt system comprises a watersuit and at least one adjustable belt attached to the watersuit, which provides an adjustable tightness around a user's mid-section. The improved watersuit also comprises an upper-body portion, a stretchable portion, and a lower-body portion, wherein the stretchable portion is more elastic than the upper and lower-body portions of the wetsuit. The improved watersuit further having a wetsuit arm positioning system, wherein the arm portions of the watersuit have extra buoyancy sections that wrap about the arm. These extra buoyancy sections are narrower around the front of the arms and wider around the back of the arms so as not to inhibit movement in the elbow region.
