When you eat it on the slope, your pants likely take the brunt of your fall. That’s why durability and waterproof capability trumps all. Marmot’s Mantra Pant ($225, marmot.com) has a special breathable duo-layer membrane that beads away water and reduces internal condensation for maximum comfort. Stick your pass in the zippered hand pockets and unzip or zip the interior vents for extra airing. The adjustable snap closure at the waist ensures it fits snugly around your core.
