Modular. The Flylow Iceman Men's Coat is not only a stretch shell fabric with a 20k waterproof rating filled with lovely down but it goes from weekend mountain warrior to an around town winter jacket thanks to a removable helmet compatible hood and a zip-out powder skirt. Robust for shedding weather, yet easily packable trekking. When the Pertex® Quantum Air lining isn’t moving enough heat for you big 12” vents give you massive air movement for thermoregulation. A great technical down jacket for mountain sports with the versatility to be your daily driver… throw the powder skirt in the gear bag so it’s always where you can find it, this is one parka you’re going to get to use every winter day, whether you’re off to work, or headed to the mountains for a day of shredding the slopes. A stretch down jacket that stretches the possibilities!
