The newly updated Trailbreaker II Pants provide the perfect amount of weather protection where you need it, and let moisture escape where you don't. A durable Pertex® Shield 2L lower leg provides complete waterproof protection to protect you where you're most exposed to snow - whether setting the skin track or breaking the trail. Plus, the Trailbreaker II Pants feature an updated waistband that's amplified by ActiveTemp, the thermo-regulating technology that adjusts to your body temperature to keep you cool, dry, and comfortable during high-exertion activities.
