The GORE-TEX Stretch Prism Snow bib is an insulated bib made for high performance on our sticks or boards. The 2-layer GORE-TEX stretch fabric is highly waterproof and breathable with plenty of stretch to maximize our comfort and mobility on the mountain. The Primaloft Black Eco insulation adds lightweight and breathable warmth for those frigid days that provide the best powder with its premium synthetic fill that's much more tolerant of ice snow and sweat than down. We also like the side zippers which make it easy to get in and out of the bibs take a short bathroom break and add a little ventilation.
