The secret to this base layer lies in the Magic Mesh fabric which is highly stretchy but does not contain Lycra (which tends to hold in the moisture). A close fitting base layer is more efficient at wicking sweat away so be sure to choose your size carefully to ensure maximum benefit from your purchase.
The Core Mesh 3 Sleeveless is designed for use in the Summer months and Castelli have intentionally made this product as minimalist as possible to let the open-mesh fabric pull moisture away from the skin - so you stay drier and cooler. In contrast to earlier incarnations the Core Mesh 3 features a wider neck for better cooling. This, in turn, also allows it to sit better under an aero jersey so you'll feel great - and look even better - at the end of the day.
