I'm not a skier. I bought these for dog-walking because I was tired of freezing all the time during this horrible winter. ( i live in Michigan. We had a record amount of snow and it was extremely cold.). These are great! They are very well made. heavy with lots of zippers and velcro. I would suggest buying your normal size. The straps are adjustable. The legs have two layers at the bottom, an inside one to tuck into your boots, and then a layer that goes over your boots to keep the snow out. My husband has an expensive pair of bibs (for dog walking and snow shoveling) and he was very skeptical about my Overstock purchase. But when they came he was impressed. They are as well-made as his expensive ones, and as heavy and warm. I expect to have these forever!
