Speedo's range of jammers offers a smooth, sleek outline in the water. A longer leg length creates a comfortable short for both racing and training. Part of the Endurance plus range for the competitive swimmer, Endurance Plus is an exclusive Speedo fabric, which resists chlorine, snagging and fading longer than any other swim fabric. It has a lower level of moisture absorption, drying faster after swimming. Featuring 4 way stretch technology for added softness and comfort.
