Product Information
Full details
The Castelli Core Seamless Base Layer is designed for adult cyclists and active individuals who need a reliable moisture-wicking garment for cool to mild conditions. Its primary benefit is the specialized polyester and polypropylene blend that keeps the skin dry by minimizing moisture retention, making it perfect for high-intensity efforts. The main caveat is that it is strictly optimized for 15°C to 25°C, meaning it may not provide enough insulation for truly cold or winter weather.
