The Swix ProFit Jacket is a high-level, technical, slim fitting soft shell jacket that will block wind, breathe and leave your mobility uninhibited for Nordic skiing, snowshoeing, running or biking. Side and back stretch panels and pre-shaped sleeves allow generous arm movement. The front face of the jacket blocks wind with three light weight layers, while the back stretch panels breathe generously. "Laser cut" perforated underarm ventilation allows for 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 ProFit Jacket is water and wind repellant with waterproof zippers, stretch inner cuffs and a drawstring hem to keep you warm and dry.
