Castelli Pro Mesh Sleeveless Baselayer

Castelli employs a 3D mesh fabric for their Pro Mesh Sleeveless Baselayer which not only maximises surface area for moisture wicking but allows excellent airflow over the skin, boosting sweat evaporation for a cooling effect. During summer this will keep you more comfortable as the temperatures rise and even when worn under a winter base layer the Pro Mesh will ensure you don't get clammy from excessive sweat build-up. Castelli gives it an eye-catching print too, it may seem superfluous, but hey, it's perfect for showing off this special base layer when you unzip your summer jersey.
