Castelli Core Mesh underwear 3 2025

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 the sweat to evaporate.

Elastam's 10% content makes it very elastic and helps to maintain condensation in order to always obtain cooling by evaporation.

L'lighter and more breathable intimate makes sweat evaporate from your skin, while the open net helps to keep the shirt not in contact with the skin. It works well even when it is hot and some runners even use it with torrid days because it allows the air to circulate between the shirt and the skin.
