éThis jammer utilises Endurance+ fabric. This fabric is exclusive to Speedo and resists chlorine, snagging and fading longer than any other swim fabric. Endurance+ contains no elastane and so is 100% chlorine resistant, so will not degrade in chlorinated water. Add to this the lower level of moisture absorption, for faster drying qualities, and you are left with a fantastic, high performing material. *Drawstring waistbandé
