This started with Castelli's favourite bibshort, the one they reach for every ride. But staying still isn't in Castelli's nature. Driven by Castelli's obsession with performance, design, and innovation, they looked for every opportunity to refine. Subtle adjustments in fit, improved construction details, and fabric updates to Castelli's bib straps that push comfort and efficiency just that little bit further. Not a revolution, but a series of gains that add up on the road.

The result? The best bibshort Castelli has ever made.

• Castelli-engineered Espresso Doppio fabric for comfort and perfect fit
• Progetto X2 Air Seamless seat pad for all-day comfort
