It's just right for rides where comfort is paramount rather than aero-gains. It's the carefully picked mix of functional fabrics and the refined fit that give the Women's Primavera Cycling Jersey the comfort you'll enjoy. To the body, Castelli uses their ProSecco Micromesh material. Quick to wick sweat off the skin and with excellent breathability too, this ensures you remain cool and fresh as the day warms up. Meanwhile, mesh panels give a boost to ventilation and breathability too. Sleeves in Velocity Rev2 fabric, with raw-cut ends, provide a smooth and comfortable fit and a modern finish.When it comes to the fit of the Women's Primavera Cycling Jersey, it's tailored more generously than their pro racing jerseys, making it ideally suited to us amateur riders who want sleek performance but with a touch more space.

Castelli Women's Gabba ROS 2Come rain or shine, the 5th generation Castelli Women's Gabba ROS 2 won't let you down. With improved water resistance it's now even better in the rain but it still retains the brilliant breathability and windproof protection you'll love, making it great for all weather eventualities. The Gabba made its revolutionary debut back in 2010. And ever since then it's been the benchmark by which all-around cycling performance is judged. The Women's Gabba ROS 2 excels in the cold and wet, keeping you warmer and drier. But in dry and milder conditions, excellent breathability ensures brilliant comfort too. The incredible versatility has been achieved thanks to the use of two Castelli exclusive Gore-Tex INFINIUM™ WINDSTOPPER® fabrics. Gore-tex INFINIUM™ WINDSTOPPER® 205 is deployed across the front, sleeves and shoulders. This faces into the weather and offers complete wind protection, a high degree of water resistance and a brushed inner face to hold in warmth. Across the back of the jersey, meanwhile, lighter and high-stretch INFINIUM™ WINDSTOPPER® 203 gives a snug fit and outstanding breathability. When there's an injection of pace or a rise in temperatures, this ensures you don't overheat and get a chill from cold sweat. It’s water-repellent too, fending off road spray.Compared to the previous iteration the Women's Gabba ROS 2 gets some key detail improvements. In order to improve control of ventilation, the KK® Vislon® front zipper is now two-way. This lets you introduce airflow to either the top or bottom of your body. For low-light cycling, the reflectivity is now more visible and pockets to the back now hold more gear. Lastly, seams at the shoulders have been moved to the back, reducing exposure to wind and rain. The Gabba RoS 2 is a must-have for autumn and spring riding when weather conditions can change in an instant.Features:Materials: 100% PolyesterCastelli-exclusive GORE-TEX INFINIUM™ WINDSTOPPER® 205 Warm brushed water-resistant fabric on front-facing surfacesGORE-TEX INFINIUM™ WINDSTOPPER® 203 Stretch on rear-facing surfaces for greater stretch and breathabilityTaped shoulder seams for extra rain protectionTop- and bottom-opening YKK® Vislon® zipper for easy sliding, covered for additional wind and rain protection3 rear pocketsReflective panel at bottom of pocketsWeight: 215gSuggested Temperature range: 9 to 16 degrees CBuy Castelli Clothing from Chain Reaction Cycles, the World's Largest Online Bike Store.
