Castelli Prosecco R SS Base LayerThe Castelli Prosecco R SS Base Layer is a mid-weight base layer that's made for cool conditions or even high-intensity cold-weather rides where moisture wicking is a must. The hydrophilic prosecco treatment spreads the moisture out over a large area for quicker evaporation. The Castelli Prosecco R SS Base Layer is also made from two distinct fabrics, with the thinner layer used where coverage from bib-shorts is expected to prevent too much insulation to give you more comfort.FEATURESExcellent moisture management in medium weight for cool conditionsProsecco 1st Layer 100% polyester main body fabricProsecco Micro fabric where less warmth is neededAnatomical cut Conforms to the shape of your body in the riding positionFlat stitching at hemSize (cm)SmallMediumLargeExtra LargeXX LargeChest929611105110Waist8084889398Hips9498102107112Inseam8283848586 | Castelli Prosecco R SS Base Layer Men's Size Extra Large in Black
