Women's Foundation Bib Short

93 % of 100
Foundation is an incredibly comfortable undershort bib, designed to cushion and support beneath baggies on local trails, and while taking in new terrain over multi-day trips.

Have a question? We'd love to hear about your next adventure.

Model is: Height 5’7”, Hips 36.5” Thigh 21" and wears a small.


Think of the Foundation bib as a base layer for your lower half. Made with an airy, open mesh and an innovative, free-feeling chamois, Foundation invites refreshing airflow right where it’s needed, and dries fast during even intense efforts in hot environments. At the rest stop, Pull2P technology - think straps that allow things to come down, without undressing - means you won’t have to remove outer layers to take a nature break.

For extended expeditions, Foundation features two roomy back pockets to complement storage on the bike, giving you the option to wear a simple tech tee or regular top instead of a cycling jersey with storage.

    so convenient!

    I've looked for years for this short! It's exactly what I want: a liner bib short that I can pull down for bio-breaks! Just note it's still a bit of a gentle pull-down, not a yank, but the shorts are very comfy and very convenient.

    Super comfy and cool

    Not cheap but worth the price for a well-made light and breezy chamois.

    My go-to for shorter rides

    While the WK3 cargo bibs are my favourite for long rides or multi-day trips, I love these for shorter outings, especially in hot weather as the mesh design allows for lots of airflow when worn under shorts. The chamois is comfortable and doesn't budge at all!

    AMAZING! But....

    I heard some mixed reviews on these guys, mostly on the fit of the pad against the butt and the shape. Oh boy, they were SO wrong.

    Absolutely gets the job done

    I purchased these bib shorts about a month ago. I love them. They’re well made and super comfortable. I actually don’t even notice I have them on when I’m on my bike. I like how the leg cuff stays put but doesn’t cut into my skin. I’m looking forward to seeing how the mesh performs in the ...

    Foundation Bib Short

    This bib short is great for mountain biking. Lots of ventilation and good length under my mountain bike short, hits above the knee. Note the legs are made of mesh material, I didnt realize this when I purchased but it worked out. I am typically a size large but needed to size down to a medium. ...

    Sweet Bibs for MTB

    I'm a big fan of bibs for enduro / all mountain riding - I find standard chamois shorts often end up with gravity pulling down and causing them to bunch in not so pretty places, where bib shorts come up higher, stay put, and give you that nice flat yoga pants feeling. These particular bibs are ...

    It's a ghost chamois!

    I didn't ride with a chamois for years because I was more uncomfortable with the lack of air flow etc until ... The foundation bib short came into my life. Padding where you need it and fresh air where you don't. Life changing. Now I just need a couple more for daily riding.
