We love that the 686 Geode Thermagraph Bib Pants use a waterproof, breathable infiDRY 20K construction and synthetic insulation for dry comfort and increased warmth-retention when we're spending all day in frigid temps and waist-deep powder. Thanks to their unique Thermagraph Body Mapping insulation system, these pants give us the toasty comfort we want without unnecessary bulk restricting our range of motion.
