Description
The grey CASTELLI TRANSITION AIR jacket is a lightweight layer that’s easy to slip on when temperatures drop on your ride. Its 20-denier nylon microfibre fabric is almost windproof, with air permeability optimised to the level of Castelli Ristretto technology.
The ergonomic cut provides a close fit, while the high collar keeps draughts out. Elasticated cuffs and waist ensure a streamlined silhouette and secure fit, whether you’re riding or sitting at a café terrace.
Its asymmetric two-way zip (opening from top and bottom), with a Castelli scorpion-branded pull tab, lets you adjust ventilation as you ride. On the back, the reflective logo and scorpion improve your visibility in low light.
Comfortable between 10 °C and 18 °C, this Tailored-fit jacket is ideal for early starts and mountain pass descents.
