Those in between days are tough to dress for, but the Zoot Ultra Xotherm 300 arm warmers make it easy. They're designed for maximum heat retention to keep you warm whether you're heading out on the trail or the road. They also wick away sweat, so you won't get chilled while riding. The large, grippy upper arm portion makes sure they stay in place even when running or mountain biking, but are easy to take off when the day warms up.
