The bib short was created in collaboration with the Zerosbatti association of Milan, which provides immediate assistance and legal protection to cyclists in the event of an accident. We made it 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 majority of the Competizione 2 Kit Bibshort features our Vortex textured fabric. We've used a wide, stretchy leg gripper with integrated silicone to ensure a comfortable, secure fit. The KISS Air2 seat pad has most of the comfort of our top seat pad but represents maximum value. We've given the bib straps an update: the back is in mesh for breathability, while the straps are a lightweight elastic and are comfortable for hours in the saddle. The intangible part that you'll appreciate most is our 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 for your cycling wardrobe.
