We're not afraid to say that, when it comes to performance and comfort, our SL Pro Bib Shorts are some of the best in the business. They use the best available fabrics, a highly advanced chamois, and feature a level of fit that's second to none. Keeping with this no-expenses-spared theme, we scrutinized every detail of the SL Pro to ensure that it'll exceed the most demanding of expectations. And when it comes to high quality bib shorts, it all starts at the fabric.
