Polartec® Thermal Pro® fabrics are made of 100% polyester yarns. They are ultra light and trap air on the surface, offering outstanding heat retention. They are also water repellent – moisture simply rolls right off.
Polartec® Power Stretch® are fabrics that are breathable and feature body hugging, four-way stretch. They keep you dry when you sweat and provide warmth without weight. Many feature a proprietary construction with a durable outer layer that is wind and abrasion-resistant and a soft inner layer that pulls moisture away from the skin.
