Castelli Special Collection With the promise of warmer weather, longer days and more opportunity to get out and ride, we’re very happy to bring you a fabulous range of Special Collection cycling kit and accessories. They’re the ideal choice to keep you comfortable and stylish on your bike this summer. Castelli Performance. Sleek Style. The Entrata SP Jersey has a classy and subtle style but its performance is something that really stands out. It makes use of three technical fabrics and marries these to a more forgiving fit giving you a technical cycling jersey that is perfect for all shapes and sizes. The main body is Castelli’s own rapid wicking and breathable ProSecco Micromesh, keeping you comfortable as the mercury rises. Mesh side panels ensure that you get the perfect level of ventilation, while a mesh silicone waistband keeps the jersey beautifully in place. Laser-cut stretch Velocity Rev2 sleeves with raw-cut edges complete this stylish jersey and give it a sleek and modern finish. Whatever your cycling ambitions, the Entrata SP Jersey is ideal for notching up the miles, whether that’s a gentle spin to your favourite cafe, taking on a challenging sportive or enjoying the rush of racing.
