- Technical swimsuits are swimsuits designed to improve your performance in competitions. The fabrics are hydrophobic to reduce drag and increase your speed. The designs offer compression which provide support, improve blood flow, and decrease recovery time. They also help stabilize your muscles during periods of high activity. Hip lift systems promote better body position and streamlining to really optimize your performance. Women’s Technical Swimsuits come in a variety of styles from neck to knee length ones to the more traditional swimsuit silhouettes to suit your preference.
