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.

I love the Fly

I bought my first pair when they launched the zipper on the back and I became a fan. Initially it took a little bit of practice to master the art of crouching+unzipping (given my lack of flexibility), but once I did, I never went back to regular bibs. They were a game changer for me, making p-stops so much more easier to handle.

Wanted to love them, but...

I've been wearing these bibs for 2 months now, on 2-5 hour rides, both road and mtb. The practicality of the zipper is fantastic, gone are the days of having to strip down to ***. The fabric is nice and fit is good, although short length is a bit long for my taste. But the chamois is the problem. It's too big and bulky. I find it creasing ever so slightly that I get irritated after every ride. Really wanted these bibs to work, but sadly they don't for me.

Best bibs ever!

You can’t go wrong with these. Yes they are tight fitting but were true to size based on chart and description. I am 140lbs and purchased a medium.

Best bibs ever.

I highly recommend the Signature Fly Bibs. After trying the other bibs Velocio sells these were the most comfortable. The fit, structure and material used gives these bibs a nice design, comfort and balance. I have 3 of them and use them often. Worth then money. The only thing I would recommend Velocio adding to these bibs is offering 2 different length sizes from the in- seem to the leg. I’m 5’4 but some riders may have shorter legs. Therefore, an inch shorter as an option would be nice.
