The Swix ProX Jacket is a slim fitting elite performance soft shell jacket that won't inhibit your mobility for Nordic skiing. Shaped sleeves plus side and back stretch panels made from special Italian lycra (that stretches to 500 times its length) allow generous arm movement. The Swix ProX Jacket is water and wind repellant with waterproof zippers, stretch inner cuffs, and an elastic drawstring hem to keep you warm and dry. As a safety feature for those who like to get out on the track in the early morning or around dusk, reflective details increase visibility in the dark. "Laser cut" perforated underarm ventilation offers increased mobility and air flow while a wicking mesh lining keeps your comfortably dry. The Swix ProX Jacket is great looking and goes perfectly with the Swix ProX Pants.
