Norrøna's zip-in ski/snowboard Bib was designed to be the perfect addition to fit their mountaineering pants for extra protection.
They use a durable flex1 stretch fabric 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.
