A Legskin is a type of competitive swimwear worn by male swimmers. Most legskins are made of technologically advanced lycra-based fabrics designed to hug the body tightly and provide increased speed and decreased drag resistance in the water.

The legskin covers from the swimmer's mid-waist to his ankle and resembles leggings. One advantage of the legskin over other suit styles that cover the arms is flexibility, especially for strokes that require broad arm movement.

Most competitive swimwear brands such as the Speedo Fastskin line, Arena Powerskin, and Tyr Aquashift include suits of this type. The price is often more than €100.

Mud Races

Another popular use for legskins (or running tights) are cross-country running and swimming events, including mud runs. These legskins are usually made of thicker material, which is more robust than those finely tuned racing tights for pools.

Add socks, shoes and a T-shirt and you're ready for a wet outdoor fun run.
