The Rab Bigline Bib is a purpose-built ski-touring bib engineered for skiers who earn their turns. It pairs weatherproof protection with a breathable, mobile fit so you stay dry and comfortable from the skin track to the summit and all the way back down. Weatherproof protection: Sheds wind, snow, and moisture to keep you dry through changing mountain conditions. Breathable performance: Vents heat and moisture on high-output climbs to help regulate temperature. Freedom of movement: Articulated, stretch-friendly construction moves with you over technical terrain. Bib design: A supportive bib front and adjustable braces seal out snow and add coverage on deep days. Ventilation: Zippered vents let you dump heat fast on the climb without stopping to delayer. Reinforced protection: Hardwearing scuff guards at the lower leg stand up to ski edges and sharp hardware.
