The Rab Bigline bib pant covers full-height without slowing your knees down, thanks to ramped-up articulation built for a dynamic ski style rather than a stiff, standing stance. A stretchy Matrix back panel adds breathability and range of motion through the torso, so the extra coverage does not come at the cost of movement on demanding terrain. A 3-layer Pertex Shield fabric still handles the waterproofing underneath, shedding powder and spindrift on the way down. What Our Gearhead(R) Experts Are Saying:"I dropped into a steep, technical line and never felt the bib fighting my knees on the turns, even with full coverage up to my chest. That's the part that usually gets sacrificed on a bib this protective."
