Our Amnicon line is made from Polartec® Power Wool™ and High Loft™ with wool. Unlike blended fibers, Polartec® utilizes a bi-component knit that places the wool and polyester threads where they can be most effective. Power Wool™ is a lightweight and thin fabric with a durable polyester exterior and a soft and odor resistant merino interior grid. High Loft™ with wool is a thick midweight fabric with a durable polyester backing weave and a soft, fuzzy and odor resistant interior and exterior merino. This unique integration of synthetic and natural fibers allows us to make a best-of-both-worlds garment.
