ATHLETIC WOOL IS KIND OF A HOAX
Athletic wool is a performance fabric, thanks to some clever marketing. The companies using wool boast that their fabrics are naturally breathable, water resistant, are great at wicking, help to regulate body temperature, and are odor resistant. This could be true if the fibers are without treatment. But they use chemicals to treat the wool. The sad reality is that the fibers undergo so much processing, they lose all of their natural characteristics.
If your wool is not processed naturally you will not get all the great benefits of wool.
Choose wisely and environmentally healthy.
