Cooling Fabric
POLARTEC® DELTA™
When hot, dry air passes through water it cools down - this is the basic premise behind Polartec’s state-of-the-art “Delta” cooling fabric.
Hailed as “the ultimate hot weather adventure fabric”, Delta weaves both hydrophobic and hydrophilic fibres in a radiating pattern to form a 3D structure. This radiating pattern creates channels through which the hydrophobic fibres draw perspiration away from the body, the hydrophilic fibres then distribute this moisture across the fabric surface and hold on to it.
As a result, Delta holds moisture next to the skin without the uncomfortable experience of feeling wet. Hot air then flows through this moisture held on the fabric and cools, thus enhancing your body’s natural evaporative cooling process. Polartec call this “metabolic cooling”.
