Norrona ski/snowboard Bib is made to fit our mountaineering pants. They are stretchy and comfortable, making sure your pants stay in place. They have a full length front zipper and a little pocket on the side.Depending on generation, there might be a +/- 2 cm potential mismatch on the same size. This will show in the front, but function will be the same. It might not be a perfect match but the function will still be there.
