It's not too hot and it's not too cold but you need a base layer to help draw sweat away from the skin for improved comfort. This is where the Pro Issue Sleeveless Base Layer excels.

Dry is Good

This is the piece that Castelli pro riders requested for those inbetween conditions where the Flanders baselayer is too warm while the Core Mesh is just too cool, like Spain in February or Belgium in April. You’re not looking for warmth from your base layer, just something to move the moisture away from your body and help your race jersey perform. Castelli's 3D mesh fabric creates dead air space next to your skin, while the polyester capillary action moves sweat away for excellent comfort.
