SPEEDY ENDURANCE. We get a lot of requests for a mid-range performance short, and this one is special. Our Endurance Evolution fabric is a high-modulous very flat Lycra® fabric that feels extremely dry while giving just the right amount of compression. The waist construction eliminates stitching and elastic and lies completely flat. We use the GIRO3 leg band from our premium shorts and put in the freshly updated KISS Air2 seat pad.
