Designed in the Speedo Aqualab, Speedo collaborated with the world’s top swimmers and coaches, as well as experts in the fields of physiology, biomechanics, and computational dynamics. By examining how water flows around a body in motion, Speedo found a hybrid of two exclusive fabrics, Fastskin and Flexskin, that reduced drag and maximized performance. The characteristics of the fabric mimics the dermal denticles on a shark’s skin, whose shape, roughness and texture correspond with changing surface water flow. It’s a suit fine-tuned for one purpose: to help you go as fast as you can.
When compared to the 1st Generation Fastskin, the male Fastskin II full Bodyskin has 4% less drag, while the female Fastskin II has 3% less drag.
