Castelli.
Active Cooling Sleeveless.
Looking for the perfect base layer when road biking on hot days? This sleeveless top made with Polartec® Delta™ provides evaporative cooling without the cling.
Worn directly on your skin, its hydrophilic and hydrophobic yarns hold a bit of moisture next to your body while the open knit allows free airflow through the fabric, keeping you cool and comfortable when temperatures rise.
