FABRIC: Thick brushed polyester fleece provides warmth where you need it most, while also excelling at moisture control to keep you dry. Gripper elastic at waist for a good on-bike fit, which eliminates draft.
SIZING: Castelli products have a close-to-the-body fit to maximize aerodynamics and performance. For a less compressive feel, or if your measurements fall between sizes, we recommend that you size up.
