With the Aero Race 8S Women's Jersey the S stands for speed, since it's the fastest Castelli has ever made. It's been primed for exceptional aerodynamics using CFD-based fabric placement and seam construction and features ribbed shoulders, engineered to reduce drag by up to 6% while racing.

It carries Castelli's Rosso Corsa label, the sign of ultimate racing pedigree and quality, but is comfortable enough to wear for long training rides, with soft, bonded sleeve endings and smooth, stretchy, light fabric that will feel great against your skin and let the air circulate, to keep you cool and dry throughout. Meanwhile, supported rear cargo pockets will hold all your essentials and reflective tabs will help to keep you visible if your ride overruns.

Choose this jersey if you're looking to go fast and concentrate on the road ahead, rather than thinking about your clothing.
