Polartec® Alpha® was invented for the U.S. special forces.
They required a superior insulation system for extreme temperature variations and the start-stop conditions of combat. Alpha® active insulation is engineered for consistent warmth, while allowing greater breathability during activity. This air exchange technology creates sustained comfort without shedding layers, which isn’t an option during a mission.
Regulate Comfort in Changing Conditions.
Polartec® Alpha® active insulation continuously releases excess body heat before it builds to cause saturation and discomfort.
This patented, adaptive quality is made possible through Alpha’s lofted fibers connected to a solid mesh core. And since Polartec® Alpha® is inherently hydrophobic, it resists all moisture and dries incredibly fast.
The laws of warmth and motion must be respected during the most challenging ski mountaineering race in the Italian Alps, Trofeo Mezzalama. Dynafit and Polartec collaborated to create performance apparel that keeps athletes comfortable and safe despite extremes.
Outdoor training in winter places demands on what you wear. So Rottefella created the ultimate collection developed with Thermal Body Mapping™ technology. Using Power Wool, Alpha, Power Stretch, NeoShell, and Power Dry, Rottefella designed a variety of garments to keep warm and dry in all weather conditions.
Mtn Logic is a unique collaboration between Polartec fabric science and the world class mountain guides of RMI Expeditions. A pure expression of alpine workwear and the very best tools built to the specifications of mountain professionals. Using Power Wool, Alpha, NeoShell, they developed a best-in-class range of technical apparel conceived and tested by working mountain guides. Guides who depend on their clothing to be warm, dry, cool & safe. It’s a full suite of Polartec solutions for temperature regulation, breathable waterproof, and active insulation ans a process that applied over 1.2 million vertical feet of field testing, experimentation, sampling & discovery.
