Castelli obsessively tests and refines their products to provide the best fitting, highest performing Cycling Apparel for Men and Women. Maximum performance means many things to different brands. With Castelli Cycling Clothing, it means longevity of product for the commuter or cycling enthusiast as much as it means saving grams or tenths of a seconds for the high end athlete. From their use of technical fabrics and threads to innovative break throughs like the first use of windproof membranes and the first hydrophilic fabric treatment, Castelli strives to be on the forefront of technology, performance and design. The result? Castelli Clothing is like nothing you have ever seen, ever felt or ever worn.
