Core Mesh 3 Short-Sleeve Baselayer

Before you assume that all baselayers are created equal, take Castelli's Core Mesh 3 Short-Sleeve Baselayer out on a summer ride with an open mind. Rather than focusing on providing breathable insulation, a warm-weather baselayer like the Core Mesh 3 actually helps you stay cooler.

The crew-neck baselayer fits like a second skin, which allows its polyester mesh fabric to instantly pull moisture off your skin to keep you dry and cool as you heat up under an unforgiving sun and tempo. By sitting between your skin and your jersey, this fast-drying layer prevents damp fabric from chilling you when the breeze picks up in spring or weighing you down on hot summer days, regulating your temperature better than your skin alone.


  • Cool off by adding this airy baselayer to your kit drawer
  • Form-fitting cut keeps fabric continuously wicking moisture
  • Magic Mesh fabric blends ventilation with breathability
  • Nearly seamless construction for a chafe-free fit

Received used and smelly

I returned this product before using it
Size Bought:

Upon opening the box I smelled STINK! Not only the smell but you can see discoloration around the neckline as well as a rubbed large snag mark on the right center chest area. Does anyone check this stuff? I understand things sometimes get returned but DO NOT SELL THEM AS NEW give a small discount and WASH THEM BEFORE shipping. Honestly smells disgusting!
