The hmlCORE XK MICRO ZIP JACKET is essential for exercising in cooler weather. The jacket’s polyester woven fabric main is durable and helps keep the warmth in. Alongside this, the polyester woven and mesh fabric lining is comfortable and breathable. You can keep your belongings safe in the zip-up pockets, while the zip garage on the front means that your zip won’t come undone and let cold air in. This hummel® jacket isn’t all substance – the drawstring at the bottom and printed logo and chevrons add a sporty look.
