Hardwearing and highly versatile, the Theta SV Bib is built for rugged mountain conditions. Breathable and durable N80p-X 3L GORE-TEX Pro is reinforced with N115p-x face fabric in high wear areas to protect against harsh mountain environments. Fully separating WaterTight™ two-way zippers give a drop seat option and ease removal over boots and crampons. An elasticized waist keeps the cold and snow out. Keprotec™ instep guards shield from cuts and abrasion, and a bootlace hook helps keep the cuff secure. Athletic e3D fit is streamlined but accommodates layers.
