Flylow decided to design the Women's Spinx Bib Pant as an insulated option for the chilliest powder days. The light synthetic insulation is housed in a two-layer fabric that's waterproof to keep us dry when we're zooming through waist-deep powder, yet is also incredibly breathable so we don't soak our baselayers with sweat when things heat up. With a full bib cut to keep the snow out of our pants, six pockets for our mountain essentials, and a regular fit that lets us make unrestricted turns down pristine bowls of powder, the Sphinx offers all the features and protection we require for a full day on the snow.
