Staying warm during cold weather doesn't have to weigh you down when you wear the KUHL Women's The One Jacket. Incredibly comfortable, this jacket is made up of a blend of nylon, spandex and AeroKnit polyester, which gives it the perfect amount of stretch to move with you while you enjoy winter activities. An internal drawcord at the hem allows for a customizable fit, and zippered pockets are perfect for keeping your hands warm. Underarm gussets provide breathability and keep you from getting overheated when you're bundled up in this warm jacket.
