The women's Burton Avalon Bib Stretch Denim is a far cry from the overalls you'd see on the farm. Their denim is both waterproof and full of stretch for a flexible fit that keeps you dry in the face of stormy conditions. Coordinate your layers to match the conditions in these two-layer shell bibs. A sweat-wicking, breathable lining responds to your body heat and provides on-the-fly temperature regulation. An elastic center back panel, mesh-lined thigh vents, and a zippered drop seat all add to the comfort and convenience of these bib pants.
