The Naikoon Pants are both functional and technical. Designed with stretch fabric and straight cut, they follow your every move, and the DRY PLAY waterproof-breathable 20K/20K PFC-free membrane provides excellent temperature regulation while the Coremax lining eliminates cold spots. The jacket-pant interface, with 3 attachment points, adds to the adjustable powder skirt to provide full protection all day long. Fully-taped seams and waterproof YKK zippers keep moisture out. For even greater breathability, we added thighs zippered vents. The always-practical I-Fit System allows you to roll up your cuffs after a great day on snow, and silicone reinforcements protect these pants from your edges. Our best seller.
