Guided by the belief that perspiration impacts performance far more than precipitation, Polartec® engineered AirCore™ to offer effective weather protection by wicking moisture away from the body through the natural migration of molecules. The result is maximum ventilation and breathability, preventing excessive body heat buildup during intense aerobic activities, without compromising comfort, freedom of movement, or garment longevity. Redefining “dry” and focusing entirely on performance, Polartec® AirCore™ allows you to perform at your best even in the most unpredictable conditions.

Wind and rain protection

The unique combination of air permeability and Polartec’s nanofiber membrane allows Polartec® AirCore™ to offer effective protection from wind and rain while maintaining high breathability. This cutting-edge technology exchanges air from the inside out to accelerate heat loss and promotes evaporative cooling, the only truly effective heat loss mechanism for those engaged in high-intensity activities. The more intense the effort, the greater the fabric’s response: movement stimulates ventilation, while air helps cool the body. By staying drier and more comfortable, you can count on increased performance, driven by air and optimized for dynamic activity.

With an industry-leading moisture vapor transmission rate (MVTR) exceeding 25,000 g/m²/24h* and air permeability** of 0.4 to 1 CFM, Polartec® AirCore™ delivers unmatched performance during high-intensity activities while repelling outside water***. Plus, the lightweight material and high stretch ensure complete freedom of movement, making it the ideal choice for outdoor enthusiasts and anyone on the go.

the ideal choice for those who do not want to compromise between performance and environmental responsibility.

Polartec AirCore

Statements from Polartec managers

Ramesh Kesh, Senior Vice President of Milliken & Company and Business Manager for Polartec, said: “Polartec® AirCore™ perfectly embodies our mission of combining cutting-edge performance and sustainability. Unlike traditional waterproof, breathable membranes that rely solely on moisture vapor diffusion, our advanced 3-layer air-permeable fabric uses an engineered air core to allow controlled flow, actively removing moisture and body heat during intense aerobic activity. Not only does it establish a new paradigm in breathable, air-permeable, and weatherproof fabrics, it demonstrates our ongoing commitment to reducing the environmental impact of the fabrics we create.

Karen Beattie, Director of Product Management at Polartec, added: “With a fabric that keeps you dry from the inside, protects you from the elements, and allows you to move freely, we’re empowering people to take on their most ambitious adventures. Polartec® AirCore™ is a highly air-permeable 3-layer fabric that promotes continuous moisture vapor exchange, harnessing external airflow to ensure faster drying times, reduce the feeling of dampness, and deliver superior comfort even during maximum exertion. This is a major step forward in breathable weather protection and a concrete example of our commitment to creating performance fabrics that foster excellence while staying true to our values ​​of environmental responsibility.”
