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.

It's rare for us to use the phrase "women's cycling." It has weird overtones somehow, likely born out of a time when "women's specific design" was equivalent to let's dumb this down and put sparkles on it. That's changing. Which is why the Signature Fly collection (bibs, knickers, tights) are really the hallmark of design in women's cycling. When temps turn cooler, ride comfort calls for a bib knicker, but until now, that meant taking off a helmet to pee or using a product that compromised on ride quality.

The Signature Fly Bib Knicker begins with the foundation of our, Signature Fly Bib Short, complete with an easy-on / easy-off, mid-ride bathroom break feature. (No halters. No oddly placed seams. No jersey, helmet and sunglasses removal.) The zipper from which it takes its name can't be felt while pedaling and isn't used while regularly dressing or undressing.

It's not all about mid ride nature breaks, however. The coverage below the knee is light and protective avoiding the need for knee warmers and emphasizing fit. The unique bib upper now includes lightweight straps bordering its stabilizing mesh panel, a construction designed to rid the ride of chaffing and to bring a lighter overall feel to the bib.

Supportive and light-feeling, these are knickers designed from the ground up to meet the highest standards of performance and to make the cool-weather mid-ride stop as short as possible.

Try the Signature Fly Bib Knicker for 30 days. If you're not satisfied for any reason, send them back for a refund.
