Mindy Simmonswrote a review of Gore Wear C5 Thermo Bib Tights+ - Women's on February 16, 2019
Familiarity: I've used it several times
Super stretchy, flexible, non-restrictive fabric. I was pleased that the ankle cuffs (which don't have a zipper) fit over my big feet with no problem and were still tight around my small ankles. They are warm and block the wind well. The potty zipper is great!!! It works really well, and I like that it has the bib top that wraps around your chest providing an extra layer of warmth in the right places :) I just struggled with the fit. I ordered a medium according to the fit chart- I'm 5'8" and 140 lbs, with relatively long legs and muscular thighs/hips. I was surprised that they fit actually slightly loose in hips and upper thigh, such that the fabric folded in front right at my hip seam while riding or sitting, and and chamois moved around after a while of riding. The little gaps between the skin and the extra fabric this created also caused some annoying cold pockets of air (and made be worry about chafing..). I'm hoping that a smaller size will work, but I'm a bit worried about having enough room to pull them over my hips using the potty zipper. We'll see! In general, a GREAT winter bib if you get the fit right!
