The Thrill Of CompetitionWe made this short to incorporate as much technology as possible from our top-of-the-line pro-level race shorts at a more accessible price. And although it\'s certainly capable of weekend racing, it\'s also a great comfort performance short even if you never pin on a number.The main Vortex textured fabric and the Giro4 leg gripper come straight from our top Free Aero Race 4 Bibshort, while the KISS Air2 seat pad has most of the comfort of our top seat pad but represents maximum value.
