The Castelli Core Mesh womens base layer is the ideal first layer for staying dry in warm weather. A fully open mesh creates a layer of air between your skin and jersey and works to hold the jersey off your skin. This helps you maintain a constant body temperature.
Castelli’s Core Mesh baselayer is very lightweight so it won’t slow you down and it absorbs next to no moisture to keep you dry.
This womens specific base layer is also cut long so that it stays tucked into your shorts.
