What Our Gearhead(R) Experts Are Saying:"I reach for the Do. Di. Ci. Jacket on those brisk rides when I'm pushing hard but still want to stay protected from the wind. The breathable Ristretto fabric keeps me dry and comfortable even when I'm hammering up the climbs."We're always chasing that perfect blend of warmth, breathability and streamlined fit and the Do. Di. Ci. Jacket delivers. Designed with Castelli's Ristretto technology, it lets just enough air in to keep us comfortable without letting cold winds ruin the ride. The minimalist design fits close to the body for an aerodynamic feel, while the stretch fabrics move with us on every climb and descent. Finished with three rear pockets, reflective piping for low-light rides and a smooth YKK(R) Vislon(R) zipper for easy adjustments, it's the ultimate layer for those shoulder-season rides when we refuse to slow down.
