Castelli made this short to incorporate as much technology as possible from their 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 their top Free Aero Race 4 Bibshort, while the KISS Air² seat pad has most of the comfort of their top seat pad but represents maximum value. The intangible part that you’ll appreciate most is their knack for building in perfect fit, thanks to the Castelli pattern engineering team. This is the short that brings the best of Castelli’s know-how in building comfort performance shorts into an accessible product in your cycling wardrobe.
