The men's JKEEL PSM competition jammer was created by J-Lab to optimise athlete's performance thanks to the characteristic 3D structure made from High Tenacity fibre and finished with a special bi-component plasma treatment that increases water flow by more than 20%. Moreover, the application of a double lamination of fluorocarbon resin notably augments its hydro-repellent action. This swimsuit features a tunnel slider with a drawstring that can be adjusted as required with no risk of compromising the fabric. The costume fit guarantees every athlete comfort, lightness and the right compression. Available in sizes 18 to 32.
