Cold weather riding tight for comfort and warmth even on the harshest of days, now with Signature Fly.



Warranty: 1 Year




We’ve all been there: completely kitted up, warmth carefully preserved for the ride, all systems go and then….a bathroom stop. There’s nothing worse than the disrobing a mid-winter nature break requires. Now there’s a better way, the Zero Fly Bib Tight fights back against cold and inconvenience thanks to a no-compromise design against the elements and offers a quick option for bathroom stops thanks to the Signature Fly.

Made of two main fabrics, the ZERO uses a proprietary high stretch windproof material on the leading panels for unmatched protection while still providing excellent freedom of movement. The rear panels are made of ultra soft and breathable WinterFit Roubaix that wicks moisture on the inside and repels  on the outside, thanks to a unique knitting technology and DWR treatment, perfect for keeping the chill out event after many hours in the saddle.

Designed for all-day riding comfort, the Zero Fly Bib Tight is available with or without our custom, top-of-the-line Cytech chamois. (The chamois-less design is best when paired with our Signature Fly Bib Shorts.)

More hours riding.

More options for places to go.

Made in



Chest - Start by placing a measuring tape around the largest part of your chest. The tape should be flat but not too snug.

Waist - Your natural waist lies between your bottom ribs and hip bones, close to the navel. To measure, breathe deeply, relax your stomach and lie the tape measure flat around your waist, allowing for a ¼ inch of slack.

Hips - To achieve the most accurate hip measurement, find the widest point of your hips and place the measuring tape around. The hip bone often isn't the widest point - it's one to two inches lower, where your butt is at its fullest.

    These bibs are the absolute best. I have worn them in temperatures down to 15F with wind and I stay warm. Best thing, is that they are so soft inside they are like puppies rubbing against your legs with each pedal stroke – even after many wears and washes. The Superfly zipper is enough to make this purchase over any others, making potty stops warm even in cold weather!

    My boyfriend got these for me after I kept raving about the Superfly bib knickers I bought a few months ago. These tights are awesome! In rainy Seattle, they are key to staying warm on crummy days. They are very comfortable and the chamois is awesome. The only lament I have about these is that the Superfly feature doesn’t work as well as on the bib knickers, I think because of the thicker, fleece fabric. If the zipper was 1″ longer (or if I was a bit shorter) I think they’d be even better. I’m 5’7″, 135 lbs (fairly slim through hips and thighs) and the small size fits snug, but I think it’s perfect like that. These have changed my winter riding game, for sure!
