Surly's 100% Merino Wool Lightweight Jeresy keeps you cool when the temps climb, and it's warm in cold weather even when wet. Because wool is antimicrobial and wicks fantastically, it doesn't stink. And that's good for everyone. The classic accoutrements are all there, too: a full-length zipper and a zippered kangaroo rear pocket that's accessible from both sides. Simply put, this is destined to be your favorite jersey!
