DC Collective Bib'n'Brace 2020 - BlackDC Collective Bib'n'Brace DC Collective Bibs throw some serious style on the most protective snow pant configuration: the bibs. These have a Weather Defense 15 waterproof and breathable membrane and are made from a stretchy, tough fabric. The stretch is perfect, because they're cut a little on the slim side not stretch pant tight, but more tailored than a workwear inspired cut. They're free of insulation, so you can add layers as the mercury dictates.
