The avid cyclist trades in his cycling jersey for a cycling jacket when the days get shorter and the temperatures drop. Cycling outdoors is possible all year round, as long as you wear the right clothing. A winter jacket keeps your body warm during your winter ride. Made of water- and windproof materials that protect you from the elements. Or a thin version for over your cycling jersey that protects you from wind and rain on milder days. And they're easy to slip into your jersey's back pocket.
