Care Guide
Washing instructions are printed on a white tag inside each piece of clothing. Following these instructions will help make sure that your gear will last as long as possible. Careful washing and maintenance will ensure the highest performance from your Castelli products and extend their useful life span.
  • Always read the care label before washing a piece of clothing.
  • Close all zips and Velcro fasteners and turn the garment inside out.
  • Hand or machine wash on a lukewarm permanent press cycle (max. 30°C / 86°F)
  • Use a small amount of liquid or powder detergent, not other products that contain fabric softeners, conditioners, stain removers or bleach as they will affect garment performance.
  • Hang dry or dry flat. Do not tumble dry.

Advanced Cooling for Hot Rides

Overview

Introducing the Active Cooling Sleeveless Baselayer by Castelli, a high-performance base layer designed to actively cool you on hot days through evaporative cooling. Engineered with innovative cooling technology, this baselayer keeps you comfortable and helps regulate your body temperature during intense rides in warm conditions.

Stay Cool with Evaporative Cooling: The Active Cooling Sleeveless Baselayer is designed to hold a bit of moisture close to your skin, creating an evaporative cooling effect. The hydrophilic and hydrophobic yarns used in the fabric enable the base layer to retain a small amount of moisture while allowing free airflow through the special open knit construction. This combination ensures that moisture on your skin evaporates, actively cooling your core and providing relief from the heat.

Enhanced Cooling Technology with Polartec® Delta Fabric: The base layer is crafted with Polartec® Delta fabric, which features regulated drying properties. This means that the fabric efficiently manages moisture and accelerates the evaporative cooling process, helping to keep your core temperature down even during intense rides in hot conditions. The advanced cooling technology of the Active Cooling Sleeveless Baselayer makes it an ideal companion for Castelli's coolest jerseys, such as the Climber's or Superleggera, although it can be worn under any breathable jersey for added cooling comfort.

Sleek and Minimalist Design: The Active Cooling Sleeveless Baselayer features a sleeveless design and minimalist construction, ensuring maximum freedom of movement and a lightweight feel. The absence of sleeves reduces bulk and allows for better ventilation, enhancing the cooling effect of the baselayer. The baselayer also boasts a sublimated overprint, adding a touch of style to your cycling apparel.
