The GORE-TEX 3L Pro Shell fabric of the Arc’teryx Theta AR Bib pants is tough, extremely breathable and durably water- and windproof. Gore Micro Grid lining is a thin, low-denier, low-density woven fabric that allows the shell to slide easily over mid layers.

The low-cut front bib of the Arc’teryx Theta AR Bib Pants features a rear elastic waist, front fly with watertight zipper and snap closure, and quick-adjust suspenders. Exposed, watertight side zippers stop short of harness/hipbelt area and provide easy access for adjusting ventilation. Laminated powder cuffs offer ample coverage and stay in place via elastic grippers and boot-lace hooks; while reinforced Keprotec hems guard against abrasion.
