I love bib shorts. I wear Pearl Izumi bib shorts in sz m. I wanted to give the Gore shorts a try because of the unique bio break system. I had trouble with the Gore sizing, After 3 tries I found the sz l to work best. The zipper system works well but the straps aren't as comfortable as the Pearls. I did not like the white on the bottom of the leg openings. It put me in mind of a Penguin. The bibs gave me a funny shape....penguin like? When paying over $100 bucks for shorts I want them to fit well and if at all possible look good on me. I am short, busty, over 60 with a body going south but happy to still be riding.
