The Burton GORE-TEX Avalon Bib Pant uses a 2-layer GORE-TEX polyester plain weave fabric construction to keep us dry and warm as we rip it up on the mountain without sacrificing breathability. With a regular fit, there is plenty of room for baselayers without being too baggy, and the elasticated center back panel offers exceptional stretch to keep us moving around with ease. The zippered drop seat allows for easy bathroom access, while several zippered and hook-and-loop pockets provide ample storage for essentials.
