Castelli Core Mesh 3 2024 Underwear Shirt

FOR THE HOTTEST DAYS
This is our underwear for the hottest days. The fabric has an open structure to create a space on the skin that allows sweat to evaporate.

The 10% elastane content makes it very elastic and helps keep condensation away so you always get evaporative cooling.

WHAT IT IS
Our lightest, most breathable base layer wicks sweat away from your skin, while open mesh helps keep the shirt off your skin. It also works well when it's hot and some runners even use it on scorching days because it allows air to circulate between the shirt and the skin.
