The key to warmth in freezing conditions, is a decent long sleeved base. And if you haven't already got a few hiding in your closet somewhere, we sense you might be interested in one...
Its main focus is to maintain your warmth, dryness and comfort, basically acting like a layer of moisture wicking insulation between your skin and jersey. Body temperature will change as you ride, so you'll find most bases are constructed using mesh panels to keep you cool and/or a fabric that's pong-free, one that reduces awful itchiness and increases your warmth and movement on the bike.
