Castelli Merino Seamless Base Layer

The Castelli Merino Seamless base layer provides the perfect balance between warmth, comfort and performance. Made for the discerning cyclist, this shirt combines a seamless construction with high-end materials to guarantee a perfect fit without irritation. Ideal for cold rides, when the breathable material will keep you dry and comfortable.

Seamless construction for optimal comfort
The Castelli Merino Seamless base layer is designed with a seamless construction to prevent chafing and irritations. The material provides plenty of warmth without feeling heavy. The use of merino wool results in excellent breathability and quick moisture wicking, which is crucial for intense rides in cold weather. This makes it very suitable for cool or cold weather.

Smart details for extra functionality
This jersey is more than a base layer. The snug fit results in a streamlined profile underneath your cycling clothing, while its light compression supports your muscles and reduces fatigue. Plus, the fabric has plenty of stretch in or to not limit your freedom of movement, which is essential on long rides. The lack of a zipper makes sure it'll retain heat, while the strategically placed ventilation zones ensure plenty of ventilation.
