Warmth and breathability in any weather. For a technical and functional ensemble to go with the Luna Jacket, the 2 layer Luna Pants feature a recyclable DRYPLAY 20K/20K membrane for maximum waterproof-breathability, and 40-g insulation that makes this the warmest pants in our Expedition range. The slim fit, high adjustable waist, and lower-back stretch fabric follow your every move. The jacket-pant interface, with 3 attachment points, enhances the adjustable powder skirt to provide full protection all day long. Taking no chances, we added fully-taped seams to keep moisture out. The always-practical I-Fit System allows you to roll up your cuffs after a great day on snow.
