Change what you wear when it’s hot. Polartec® Delta™ revolutionizes cooling fabric technology by enhancing the body’s natural cooling process—sweat.

Unlike traditional next-to-skin fabrics that wick moisture but don’t actively cool, Delta™ optimizes cooling by elevating touch-points to boost airflow, accelerate moisture dispersal, and reduce cling. Its innovative composition regulates dry times and improves breathability when wet, keeping you comfortable in hot conditions.

Polartec® Delta™ features a specialized knit construction that combines hydrophobic and hydrophilic yarns for superior moisture management. This patent-pending radiating knit structure enhances airflow and dissipates heat more effectively, ensuring you stay cooler and more comfortable even in the hottest weather.
