This women's adidas Climaheat Hydro Jacket is up to the task. We started with super-soft climaheat™ fleece, a technical fabric made with hollow-fibre polyester yarn for great insulation even in extreme cold. It absorbs less water, dries faster and stays warm even when wet. We added woven overlays on the hood, shoulders and chest for wind protection. The training jacket is finished with single jersey on the cuffs and waistband for comfort.
