The women's-specific chamois is Italian-engineered for serious saddle time. Whether it's a 90-minute hammer session or a full day in the mountains, the M1 is built to go there with you.

Climate

Cold Mild Warm Hot

Ventilated bib straps and a fabric that breathes under load — built for warm rides, long climbs, and the days when the heat is part of the challenge.

I've been through a lot of bibs looking for one that actually fits and performs on long days. This is it. Did a 5-hour ride last weekend without a single issue. These are my new favorite bibs.

— Sarah K.

Really solid bib across the board. Compression is high and supportive, fit is dialed, chamois performs well past hour three.

— Jess W.

Finally a bib that takes women's fit seriously. I did a century in these and my only focus was the ride.

— Rachel T.

The fit is exceptional. I have a hard time finding bibs that work with my proportions and these are the best I've tried.

— Lauren M.

frequently asked question

Is the chamois actually designed for women?

Yes — the M1 uses a women's-specific anatomic chamois. The shape, density placement, and dimensions are engineered for women's anatomy and women's riding position. It's not a unisex chamois relabeled — it's built differently from the ground up.
How does the chamois hold up on long rides?

That's what it's designed for. Three foam densities with a high-density insert at peak pressure points, thermo-molded for your pedalling motion. Athletes regularly ride 6, 7, 8+ hours in the M1 without issue. It's built for the long day.
How does the compression feel after several hours?

High but not punishing. The fabric provides real muscle support without becoming restrictive as fatigue sets in. Most riders describe it as feeling locked in rather than squeezed — and that hold stays consistent across the full ride.
How does it fit?

It's a race fit — snug and intentional, shaped for women's body geometry. True to size for most riders. If you're between sizes or prefer slightly less compression, go up. The bib is pre-shaped for your position on the bike.
How do I care for the bib?

Machine wash cold, gentle cycle. No fabric softener — it breaks down compression fabric and chamois performance over time. Hang dry only. Don't tumble dry.
