Castelli Do.Di.Ci Short Sleeve Jacket | Unprecedented Breathable PerformanceRedefine your performance in transitional weather with the Castelli Do.Di.Ci Short Sleeve Jacket for Men. Engineered for the dedicated cyclist who refuses to compromise, this innovative garment masterfully blurs the line between a protective jacket and a high-performance jersey. It´s the ultimate solution for cool to mild conditions, eliminating the guesswork of layering and allowing you to focus solely on your ride. The name itself, Do.Di.Ci (Italian for twelve), hints at its revolutionary core: a level of breathability that sets an entirely new standard in cycling apparel.Experience a paradigm shift in comfort and temperature regulation. The Do.Di.Ci jacket is built around the exclusive Castelli Ristretto technology, an advanced fabric created in partnership with an industry-leading innovator. This intelligent material provides exceptional wind resistance to shield you from chill, but its true genius lies in its engineered air permeability. It allows just enough air to pass through to actively vent heat and moisture, delivering a staggering twelve times the breathability of previous legendary Castelli Gabba jackets. This means you can push the pace on climbs and hard efforts without overheating, and descend in comfort without the clammy, chilling effect of trapped sweat.Designed for speed and an uninhibited riding experience, the Do.Di.Ci features a close-to-body, athletic stretch fit. This aerodynamic silhouette cuts through the wind, yet the advanced stretch fabrics ensure it never feels constricting. The jacket moves with you, offering complete freedom of movement whether you´re in the drops or out of the saddle. The minimalist construction strips away anything unnecessary, leaving only pure function and comfort. Practical details are refined for the road, including a smooth-gliding YKK® Vislon® zipper for easy, one-handed ventilation adjustments. Three spacious rear pockets provide ample storage for nutrition and essentials, while reflective piping along the bottom enhances your visibility to others in low-light conditions, adding a crucial layer of safety to your dawn or dusk rides. This is more than a jacket, it´s a piece of high-performance equipment designed to give you a competitive edge and supreme comfort on every cool-weather ride.Attributes: Men, Reflective accents, SyntheticTechnical SpecificationsPRODUCT FEATURES:Next-generation breathability in a stretch short-sleeve jacket that blurs the line between a jersey and a jacket, for cool to mild conditions.Exclusive Castelli Ristretto technology with engineered air permeability keeps most wind out, allowing in just enough to provide exceptional breathability — 12 times more than previous.Castelli.Gabba jackets.Close-to-body stretch fit doesn´t feel constricting, thanks to.Ristretto stretch fabrics.Minimalist construction for speed and comfortYKK® Vislon® zipper for easy sliding3 rear pockets.Reflective piping at bottom of pocket for visibility.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
