Adidas says that its Climawarm+ cold weather training apparel mimics the fibers of a polar bear's fur by trapping heat and drying faster. That may be a bit of hyperbole, but the Full Zip certainly gets the job done. Its THERMOLITE fabric keeps you warm during a run or an outdoor workout on a brisk day, but it also breathes so you don't drown in your own sweat. Thumb holes in the sleeves allow you to cover your hands if you so choose, and the zipper is firm enough so that it doesn't bounce around when your body is on the move. The hood can be somewhat of a nuisance, sliding off to one side of your shoulder during a run, but a slight adjustment to its tightness can take care of that issue.
