Power Wool™

Natural Performance

Polartec® Power Wool™ is a revolutionary, bi-component knit fabric that combines the best of both natural and synthetic fibers, all without blending.

The industry standard of blending wool and synthetic yarns together often hinders the greater performance qualities of each material. Power Wool™'s advanced knit construction places each distinct fiber where it can work to its highest potential. This hybrid design is made with a soft, odor reducing, merino wool base and a highly durable synthetic exterior.

The best of both threads.
