Warm in the winter, cool in the spring, trim to the body. What makes our Atomic W Savor 2L GTX pants special is they deliver in all conditions. For cold days they come with a special PFC-free GORE-TEX fabric that's waterproof, windproof and has a thin layer of insulation built-in. There's also a fleece-lined waistband. Then for spring days the GORE-TEX fabric is highly breathable. The Ski Fit has articulated knees for great freedom of movement, while staying trim and close to your legs with no flapping. Focus on your skiing- forget the rest.
