The LW Bib


Glacier Bibs, the TREW Ex Div way.

This is a bib for long days up high. We believe that softshell pants are best-suited for Aspen’s apres scene (blame our stubborn CEO); hardshells are lighter, more windproof, and more waterproof. To pull off the perfect combination of lightweight minimalism and rugged durability, we used two new hardshell fabrications: the 3L7D ultralight, waterproof shell and Vectran(R) reinforced instep protection. 

Featuring an adjustable cuff with Fidlock magnetic closures, the LW Bib can be tightened around your boots while you’re climbing and then relaxed for a more comfortable downhill fit. The storage options are minimalist: the bib upper features two options for your transceiver and the hand pockets are positioned to fit with a harness. Outseam vents are positioned to allow for maximum airflow and the ability to delayer while still wearing your boots.

    The Fit

    Designed with the minimalist in mind, this bib offers our slimmest fit.


    Our lightest and most breathable bib, the LW Bib is built specifically to keep that air flow game strong while moving fast up and down mountains.


    With high breathability comes a loss in durability, so take a bit more care around trees + edges with this LW 3L kit.
