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.

About Power Wool™ Technology

Advanced synthetics on the outer surface of Polartec® Power Wool™ transfer moisture out while enhancing durability and resilience.

Merino wool next-to-skin delivers on classic comfort, warmth, and wicking. Power Wool™’s patented bi-component knit optimizes base layer performance in more diverse conditions and levels of activity.

Power Wool™ Q&A
Wool naturally resists odor, thermal regulates, and manages moisture, all of which make it ideal for use in a base layer. However, wool also has a few negatives: it dries slowly, is prone to shrinkage, and lacks durability. Polartec® Power Wool™ employs a synthetic face yarn to correct for these deficiencies. The end result is a bi-component fabric that does everything well.
Power Wool™ uses sustainably harvested wool. Our wool supplier has committed to upholding the Farm Animal Welfare Council's "Five Freedoms" to ensure best practices for animal husbandry, including the assurance that none practice mulesing or acquire previously mules'd sheep.
