CASTELLI Velocissima 3 Bibshort The Castelli Velocissima 3 bibshort is the midrange performance short from Castelli, great for a long ride or a quick hour workout indoors or out. Their Endurance Evolution fabric is a high-modulus, very matte Lycra fabric that feels extremely dry while providing just the right amount of compression. At the leg ending Castelli use a raw-cut edge with vertical silicone strips to keep the leg in place without the pressure that creates the dreaded sausage effect. The bib straps are stretchy enough that you can pull the short down for a pee break without removing your jersey and bibs, while the floating construction allows you to cross the straps on the front or the back, whichever works better for you. A great short needs a great seat pad, and the women's-specific KISS Air2 Donna pad will keep you comfortable without being too bulky.
