Q & A

Ideal for any ride, Castelli's Active Cooling sleeveless base layer takes the moisture emitted from your body and wicks it away quickly and efficiently. This is a benefit whether riding in hot or cold weather.

In hot weather, the mesh creates a layer of air between your body and jersey, so airflow is maximised and the heat of the jersey is kept away from your skin. In cold weather, your body sweats just as much due to the warmth of winter clothing, so you need this moisture wicked away as quickly as possible to stop it getting cold.

This Castelli Active cooling base layer features energy-activated technology that provides more cooling than does sweat evaporation alone, and the dynamic print pattern shows you where its working. This ultralight base layer also provides 50 UPF, making it the perfect companion to your lightweight summer jersey.

Note: Please click on the above tabs for the Castelli size guide and technology guide.

Note: Castelli clothing is sized small, Tweeks Cycles recommend you select one size above normal for an athletic fit, or two sizes above if you prefer a more relaxed fit.
