If you have never worn wool before you are missing out on the best insulator Mother Nature has to offer. Besides whale blubber of course, but clothing made with that stuff is kind of illegal. What you’re looking at here is the Burton Wool ¼ Zip Shirt. For maximum warmth and breathability, it harnesses the naturally insulating, quick-drying, and fresh smelling powers of wool. It’s also extra long for easy tucking, stretchy for total freedom, and is even complete with chafe-free seams and a chin guard for smooth comfort against your skin.
