The Castelli Active Cooling Sleeveless base layer actively cools you making it ideal for riding in the hottest conditions.
The Polartec® Delta fabric uses hydrophilic and hydrophobic yarns. This base layer holds some moisture next to your body for an evaporative cooling effect next to your skin while allowing airflow through the fabric due to the open-knit construction. A sleeveless design reduces bulk and seeming under your jersey.
The base layer is recommended for use with the lightest jerseys, such as the Climber’s or Superleggera, but it will work with any breathable jersey.
- Base layer to cool you on hot days
- Polartec® Delta fabric for regulated drying. The evaporative effect cools your core
