Summer jerseys live and die by their ventilation strategy, and Castelli's Superleggera A/C takes a more aggressive approach than most. The entire front panel uses Fuga Leggerissimo mesh—the same open-weave fabric that typically gets relegated to side panels or underarm gussets on other jerseys. Castelli puts it where airflow matters most: directly in the path of oncoming air where it can actually move heat away from your core.
