The Castelli Transition Jacket is their lightest jacket and, as the name suggests, it is perfect for transitional months where temperatures tend to be milder, think early autumn and late spring. The fit is reasonably close as a nod to aerodynamic gains.
Rather than the fleece lining of their more traditional winter thermals, the Transition Jacket replaces the fleece lining with a lightly brushed jersey that helps wick moisture away. While this jacket provides minimal insulation, the full Gore® Windstopper® front and sleeve front keeps out chill winds and you’ll be able to layer it to cover most conditions.
Not only is it lighter weight for less-cold conditions, it also has a high degree of stretch and freedom of movement for a closer more refined fit.
We can see this being the perfect jacket for when fitness is still high but conditions are cool. A fast club ride in spring or a late summer, early autumn interval session is where this jacket will excel, when you've still got some speed in the legs, the intensity is higher and the pace is still brisk.
