Rab M Bigline Bib

Rab Bigline Bib – Shell Bib Pants for Freeride & Deep Snow

The Rab Bigline Bib is a full-height shell bib pant built for freeride skiing, deep snow, and demanding untracked terrain. Constructed with Pertex® Shield 3-layer fabric, it delivers serious weather protection while keeping weight and bulk in check. Designed without integrated insulation, it rewards riders who prefer to dial in their own thermal layering system based on conditions and intensity.

A standout feature is the Matrix™ stretch double weave nylon rear panel, which enhances breathability and freedom of movement exactly where you need it most — through powerful turns and sustained vertical descents. Articulated knees further support unrestricted mobility, while an integrated RECCO® reflector adds an important layer of backcountry safety.

Practical details are equally well considered: thigh-zip through-ventilations with YKK® zippers allow active temperature regulation, and a two-way hook-and-loop waist adjustment ensures a secure, customizable fit. Storage is generous, with two large-volume bellowed pockets and a chest pocket, all with YKK® zippers.
