Pro-level cooling.

Castelli’s Women’s Pro Mesh Sleeveless Baselayer will keep you drier and cooler than your counterparts thanks to lightweight 3D mesh; it’s three-dimensional construction increases surface area, which in turn, improves moisture management for drier, cooler, and more comfortable riding. At 42g, you’ll hardly notice this baselayer beneath your jersey. Though, its eye-catching design will garner compliments as soon as you unzip your jersey on a hot day. For bunch-free, easy layering, the hem is designed to lay flat against the torso.

Super comfy. Fits great in the boobs, which is a minor miracle.

I wear this under my jersey when it is hot, cool and cooler. Prevents the jersey from sticking to me and obviously helps evaporation. I wear a size large jersey and bought this in a medium. Worked out perfectly as far as size and function. I did notice on the first wearing that I thought the armhole was cutting in at the front of my armpit. Don't remember noticing it as much the more I wear it. Anyway, I am very happy I purchased this garment and really only did so because of the print. The base layers that are all white look dingy no matter what you do.
