MORE ADVICE
RACE FIT
Castelli race clothing – such as Aero Race jerseys – stretches a lot to achieve a ripple-free fit. It's this snug fitting that gives you the aerodynamic watt saving Castelli is famous for. If you like the design of a race piece, but want a more casual fit we recommend you go up a size.
NON-PERFORMANCE FIT
A non performance piece of Castelli apparel will come out of the bag much more like your T-shirt size. This means a looser fit than race clothing, ideal for long training days in the saddle where speed is a secondary concern to comfort.
Jackets and vests
Winter jackets are sized to fit over a long-sleeve base layer. Waterproof and windproof jackets are designed to fit over a jersey and arm warmers. Vests (gilets) are designed to fit over jerseys.
