Castelli Medio Long Sleeve Base Layer

The Castelli Medio base layer offers support during chilly rides in spring and autumn. This long-sleeved undershirt combines lightweight insulation with active moisture wicking. The result is a comfortable first layer that helps you stay dry and warm in mild to cool conditions between 4 and 14 degrees.

Material and fit
The Medio base layer is made of 100% polyester in a soft finish. The brushed lining feels comfortable on the skin and provides sufficient insulation for chilly rides. Thanks to the stretch in the fabric, the undershirt has a snug fit without being tight. The breathability ensures that sweat is quickly wicked away, which helps prevent overheating when used intensively in moderately cold conditions.

Functional details
The Castelli Medio has a round neck that fits comfortably without being too tight. The lack of seams in critical areas reduces the risk of chafing. The stretchy fabric contributes to high freedom of movement and makes the undershirt suitable for use under a cycling jersey or jacket. As the material dries quickly, the base layer does not feel heavy when used intensively or in changing weather conditions.
