Sonic Light Ribtex UW: Improved water repellency and a lighter feel in water. Shows its true value in the water. SONIC LINE DESIGN-X: Features a wide lining support area and cross-shaped support lines around the sacrum (which most reduces strain on the hamstrings) and in the internal rotation direction (further reducing strain on the hamstrings and quadriceps (front thighs)). Supports both upkicks and downkicks, and improves lining fit.
