What happens when you spend a winter riding bikes in the Sierra? You develop a Super Thermal (very warm) jersey that’s so warm, it could probably be called a jacket.

Made using a heavyweight Australian RWS certified 19 Micron Merino Wool, this is our warmest jersey made to date. We recommend it for temps below 53 degrees on its own or layered with a magic shell for temps in the 30s. Cut and sewn in Oakland, CA it features two massive rear pockets (gloves, cap, snacks, hand warmers), one zippered rear pocket, and one front zip chest pocket. The extra-fine merino wool comes with all of the antimicrobial and wicking properties you've come to expect. Reflective details are included on the back and YKK zippers are used all around.
