These long johns were great! They didn't look that sexy on me, but I thank my muffin top for that. But I wore the pants under my snowboard pants for a 14 hour hike and my legs were dry, comfortable and warm. The shirt was a nice relief when I changed my undershirt halfway up the mountain. It was warm, dry and a really welcome change from the other shirt I had been wearing. This is a great set and I'm glad I purchased it!
