Change what you wear when it’s hot. Polartec® Delta™ was created so cooling fabric technologies could better utilize the body's natural cooling process — sweat.
Next-to-skin fabrics that target wicking and fast drying will keep moisture moving, but don't work towards actually cooling the body down. Delta™ works more efficiently by elevating touch-points for increased airflow, faster moisture dispersal, and reduced wet-cling.
Polartec® Delta™ features an innovative composition that regulates dry times and allows better breathability when wet.
Delta's specialized knit construction uses both hydrophobic and hydrophilic yarns for more advanced control of moisture dispersal. These patent-pending radiating knit structures keep you cooler in hot conditions by increasing airflow to dissipate heat.
