Our Faluun Sweater is made from Polartec® Alpha Direct – a fabric originally developed for military use. What makes it special: It is lightweight, breathable, and still reliably warm, even during activity or in damp conditions.

What is Polartec® Alpha™?
Polartec® Alpha™ is innovative active insulation that adapts to changing conditions by effectively regulating warmth and moisture. Originally developed for U.S. Special Forces to effortlessly handle the changing phases of activity and rest during missions, Polartec® Alpha™ is available in various lightweight versions and can be worn directly against the skin. It keeps you warm when needed and releases excess heat during intense activity – ideal for all types of outdoor pursuits.

What is active insulation?
Active insulation refers to Polartec® Alpha™’s dynamic ability to seamlessly insulate the body and regulate thermal management during high physical activity, while also keeping you warm when you are less active.

How does Polartec® Alpha™ work?
Polartec® Alpha™ uses a lofted fiber structure with a mesh core that traps warm air when needed, while also allowing for increased airflow during activity. This active thermal management system prevents overheating and ensures comfort in unpredictable environments.

How does Polartec® Alpha™ differ from conventional insulation?
Unlike traditional insulation, which indiscriminately traps heat, Polartec® Alpha™ offers dynamic breathability, short drying times, and moisture resistance. By actively adapting and automatically responding to your activity level, it keeps you comfortably warm – without the risk of overheating.

What are the key benefits of active insulation?
Active insulation Polartec® Alpha™ can be worn in a significantly wider range of activities and conditions than traditional insulation materials such as synthetic fill or down, which are more suitable for static situations. Polartec developed its active insulation technology to effortlessly handle the changing conditions between movement and rest. With its active airflow system that adapts to temperature fluctuations, this body-hugging insulation technology particularly excels when it is truly put to the test.

How durable is Polartec® Alpha™?
Polartec® Alpha™ was specifically developed for high durability. Its robust structure maintains its thermal performance and breathability even with repeated use and frequent compression over a long period.

We love Alpha™ Direct because it combines functionality with comfort – and because it's durable, easy-care, and ideal for anyone who enjoys being outdoors. A fabric that simply works – day after day.
