Product Story

Product details

Advanced Breathability and Comfort

The CASTELLI Do.Di.Ci Short Sleeve Jacket features Castelli's exclusive Ristretto technology, providing 12 times more air permeability than previous models. This engineered air permeability allows a small amount of air to pass through the fabric, significantly enhancing sweat evaporation and keeping you dry during high-intensity rides.

Designed for Speed and Functionality

With a minimalist construction and close-to-body stretch fit, this jacket offers speed and comfort without feeling constricting. The fabric is extremely stretchy, ensuring an unparalleled fit. It includes a YKK® Vislon® zipper for easy sliding and three rear pockets for storage, with reflective piping at the bottom of the pockets for enhanced visibility.

Innovative Fabric Partnership

Castelli partnered with fabric innovator ITTTAI® to create an exclusive fabric combining advanced stretch, breathability, and water protection through ITTTAI®’s membrane and lamination expertise. While the jacket offers some protection against road spray, it is best suited for dry conditions. For rain, additional outerwear is recommended.
