The Swix ProX Women's Jacket is a flattering elite performance soft shell jacket, perfect for aerobic winter sports such as cross country skiing, running, biking and snowshoeing. The front panels are three layer laminated stretch membrane to block wind, and the side and back stretch panels made of breathable Italian 4-way Lycra (which stretches to 500 times its length) and pre-shaped sleeves allow generous arm movement. Wicking mesh lining keeps you comfortably dry even when you're working hard, and "laser cut" perforated underarm ventilation offers increased mobility and air flow. As a safety feature for those who like to get out in the early morning or around dusk, reflective details increase visibility in the dark. The Swix ProX Women's Jacket is water and wind repellant with waterproof zippers, stretch inner cuffs, and an elastic drawstring hem to keep you warm and dry. It goes great with the Swix ProX Women's Pants which feature all the same technology to help you perform while looking sharp.
