Torso arch support for use in aquatic sports

A wetsuit, comprising:

• a garment, having:
• a torso wedge having a backside, a frontal section having top, middle, and bottom portions, and raised side-walls for torso support when worn in a prone position on a hard surface;
• the backside of the torso wedge is concaved and commensurately contoured to absorb pressure from a curved middle section of a user in a prone position;
• the frontal section of the torso wedge is elevated having a varying gradient that is reduced from the top portion to the bottom portion of the frontal section, and is further concaved throughout the gradient from top to bottom, and laterally, thereof;
• the top portion of the frontal section of the torso wedge is comprised of an arched apex plateau that conforms, supports, and spans a proximal width of a costal arch of the user's lower rib cage, elevating a torso of the user when in the prone position on the hard surface to reduce user upper and lower back exertion;
• the middle portion of the frontal section of the torso wedge is lower in gradient than the top portion, with increased concavity in relation to the top portion for better distribution of the user's mass across the hard surface;
• the bottom portion of the frontal section of the torso wedge is lower in gradient than the middle portion, with decreasing concavity in relation to the middle portion for better distribution of abdominal mass of the user across the hard surface;
• and
• the side walls of the torso wedge are comprised of concaved, slanted edges having varying heights that vary commensurate with the gradient of the frontal section, and a side wall top integral with the arched apex plateau of the top portion.
