Product Story

Product details

Advanced Breathability and Comfort

The Castelli Do.Di.Ci. Jacket features exclusive Ristretto technology that provides 12 times the breathability of previous jackets like the Gabba. This engineered air permeability allows a small amount of air to pass through, effectively evaporating sweat and keeping you dry during high-intensity rides.

Optimized for Cool Conditions

Designed for cool to mild weather, the jacket is optimized for temperatures between 8°C and 15°C (46°F - 59°F). Its lightweight 212 g construction dries quickly and supports sustained efforts.

Race Fit and Functional Design

Close-to-body stretch race fit that allows full freedom of movement without feeling constrictive.
Minimalist construction for speed and comfort.
YKK® Vislon® zipper for easy venting on the fly.
Three rear pockets with reflective piping for visibility and storage of ride essentials.
Windproof fabric that blocks most wind while allowing breathability.

Fabric Innovation

Castelli partnered with ITTTAI® to develop a fabric combining advanced stretch, breathability, and water protection through membrane and lamination technology. While not fully waterproof, it resists light road spray and is best paired with additional rain gear if needed.
