You're crankin' hard to stand on top of that podium, so you need a warm-up and training jacket that can hang in there with you. The Swix Men's Star X Jacket fits the bill. Its polyester shell has an ecologically friendly DWR coating to resist water without using fluorocarbon chemicals that harms the environment. Stretchy panels in the back, sides, and elbows offer better flexibility and air circulation, and the mesh lining increases this jacket's breathability. Laser-cut ventilation under arms and on upper back will dump heat, but before you work it up, you can cinch the elasticized hem and collar with drawstring to keep your warmth on those chilly mornings. When you take the Star X our for a run before or after the sun is out and about, the reflective mesh and piping will help you shine like a star.
