Constructed from 100% recycled polyester, this sleeveless layer actively wicks sweat away from the skin to regulate body temperature and prevent overheating. Its soft, breathable fabric is designed to sit close to the skin, providing a comfortable barrier under bib straps and jerseys to prevent chafing during high-intensity efforts. Designed for versatile performance, this base layer integrates seamlessly under any jersey in the Rapha range. The lightweight mesh-like structure ensures maximum airflow while maintaining a compressive, ergonomic fit. Whether you are tackling steep climbs in the heat or embarking on long summer endurance rides, this sustainable layer provides the moisture management needed to stay cool and dry.
