Castelli Core Mesh Short Sleeve Base Layer
Castelli's Core Mesh Short Sleeve base layer accomplishes a critical job with next to no weight. Its fully-open mesh fabric works to hold your jersey away from your skin, creating a layer of air that helps you to maintain a constant body temperature even when you're cranking up a steep hill or riding hard on a blistering hot day. The fabric absorbs almost no moisture so it won't get logged with perspiration and weigh you down and the lack of seams make this short incredibly comfortable against your skin. This base layer is soon to be piece of warm weather gear you won't ride without.
