Castelli WRC Custom Core Mesh 3 Sleeveless Baselayer

This is our base layer for the warmest conditions. The mesh is open to create a space on the skin for sweat to evaporate. The 10% elastane content makes it very stretchy and helps in the moisture retention so that you're always getting evaporative cooling.
