Fantastic Bib; Fly works

I have other Velocio bibs without the fly and love the quality and chamois. The fly works and is fantastic. This weekend I wore them to bike in 32 degree weather. On top I wore a thermal base layer, two other shirts, arm warmers and a jacket; on the bottom these bibs, and two pairs of full tights. (Ok, ok, there was a head wind too and I get cold.) I was able to go to the bathroom in these without taking ANYTHING off. It was amazing. It would have taken me 10 minutes to go to the bathroom otherwise and I would have frozen in the process.

Love the Bib. Adore the Customer Service

This is my third, count it, third purchase of the Fly Bib Short. When it comes in the mail in the lovely packaging and then you feel the silky straps I no longer felt I had to choke on the amount of money I just spent. . Then you wear them and not only do they feel like luxury you can *** without taking everything off. As important, this go round I ordered a pair that were on sale and they didn't come packaged the same and didn't feel the same. Even though I wore them and didn't feel good about returning them the customer service rep. said send them back. When I said please send me a black pair and charge the extra she said absolutely not! We will not charge you the extra. Delivered just a few days later, in the lovely packaging, my new, silky feeling, best Bib shorts ever. Thank you Velocio for making these and for honoring and going beyond your customer service promises.

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.
