I haven't had the same problems as the other reviewers. I ordered a large due to being 6'3" and the straps are perfect. I also have fairly big legs and I really appreciate the way the leg bands fit. Very comfortable.
That being said, they put the tag on these in the worst place imaginable, right in the ol' coin slot. Just move it up an inch, or put it pretty much anywhere else. I loved the bibs but hated the way they rubbed so I removed the tag. Should you go to the same effort please don't be like me, use a scissors. Don't rip it out. I now have extra ventilation where the tag used to be and I've had to avoid wearing these in public to keep my modesty.
That being said, they are always under my mtb baggies because they are so, so comfortable. The chamois in these is brilliant. The've also made some appearances in basement trainer sessions where the extra ventilation can be kind of nice.
