Norrona's zip-in ski/snowboard Bib was designed to be the perfect addition to fit their mountaineering pants for extra protection. A durable flex1 stretch fabric is used for this bib because it offers flexibility in size, durability, breathability, snow and wind protection. The fabric is a recycled 85% nylon and 15% Elastane (BLUESIGN approved) 163 g/m2, to make this bib durable and flexible enough to not stand in the way of your mobility. Additional features include: Zip-in to our mountaineering pants, suspenders that can be quickly adjusted., extra pockets on the front and side for storing your valuables. Depending on the generation, there might be a +/- 2 cm potential mismatch on the same size. It might not be a perfect match, but the function will still be there. The zipper length for matching the pants has these measurements per size.
