Size: S, Cold weather rides require some planning, and for some that means bringing along extra gear like arm and leg warmers. We prefer to keep things a bit simpler, balancing individual pieces of kit that fit the bill for a variety of conditions, like Castelli's Velocissima shorts. These shorts are designed to trap heat, thanks to their Thermoflex fleece construction, but fall to a perfect mid-calf length so you can still stay cool enough when temperatures rise a bit. The Castelli top employs a double-layer SoftFit waistband for a comfortable fit that stays in place without the dreaded sausage casing effect. For long-term comfort, Castelli uses their KISS Air2 Donna chamois that absorbs harsh vibrations with multi-density foam. The dense foam is placed at the thickest point of the pad under the sit bones to cushion them from the road, slightly tapered to relieve pressure on the perineum. The KISS Air2 Donna uses Castelli's softest face fabric, giving your skin a smooth touch while you ride, reducing the potential for irritation or chafing.
