With a roomy regular cut for adding base layers when needed, the Treva Pant provides reliable waterproof-breathability through our DRYPLAY 10K/10K membrane, Teflon EcoElite™ PFC-free durable water repellent treatment, Thermal STD 40-gram insulation to keep you warm, inner-leg zippered vents, and critically taped seams to keep moisture out. The jacket-pant interface, with 3 attachment points, adds to the adjustable powder skirt to provide full protection all day long. The always-practical I-Fit System allows you to roll up your cuffs after a great day on snow. A pant with a minimalist yet efficient design!
