The key to warmth from the waist down is either, to be really hairy or to apply the hair of others to the desired area. This is a fact of nature. The hair of sheep, otherwise known as wool, is generally the most accepted method to stay warm on those super cold days. Case in point, the Burton Wool Pant. For maximum warmth and breathability, it keeps your nuts nicely toasted by harnessing the naturally insulating, quick-drying, and fresh smelling powers of wool. It’s also stretchy for added mobility and even has chafe-free seams and a Softwrap Waist for maximum comfort against your skin.
