The Women’s Pro Mesh Sleeveless Baselayer from Castelli is made of lightweight 3D mesh; it’s three-dimensional construction increases surface area, thereby enhancing moisture management for drier, cooler training. At 42g, this baselayer is hardly noticeable beneath a jersey. Though, its eye-catching design will garner compliments as soon as the jersey opens up on a hot day. The hem is designed to lay flat against the torso for smooth, fuss-free layering.

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

It does what it is supposed to do

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.
