Unleash the fastest version of yourself with our Aeron Lab Polartec Short Sleeve Base Layer. We’ve joined forces with fabric innovators Polartec® to create a versatile top which keeps your core temperature optimised whatever the conditions.
The advanced open knit Delta™ fabric sees hydrophilic fibres hold enough moisture close to the body for exceptional temperature regulation while hydrophobic polyester maintains airflow to remove the excess sweat, ensuring you don’t overheat on a climb or catch a chill on the descent.
