Sportful R&D Ultralight Jersey
Designed for the hottest conditions and the biggest climbs. The semi-open mesh fabric allows maximum airflow and the low Lycra® content helps maximize evaporative cooling. The light, airy feel has us reaching for this jersey from 25° and up. Should be used without a base layer for best effect. UPF 10 rating means that it filters out 90% of damaging UV rays.
