Shorts are an obsession at Castelli and Women’s Prima Bibshort shows this attention to detail. They’re the most vital piece of clothing and one of the hardest to get right. Even though the Prima is Castelli’s entry-level short it shows that there is no compromise on comfort and performance. It starts with the women’s-specific KISS Air2 seat pad. Just the name gives an idea of the process of constant improvement which started with a soft KISS pad that was improved by making it more breathable Air and then improved again in the latest update to use the softest-ever top fabric 2. It’s ready for your next big ride indoors or out.
