I'd have to disagree with the statement that these bibs run close to US sizing. I've worn them 3 times now and although I got them in the same Small size as my other nicely-fitting bibs from Capo and Pactimo, they are much, much smaller than those. You definitely have to order one size larger than normal with these. I've had quite a bit of discomfort in the groin from these bibs pulling too tightly. It's not the width of the leg, etc. that's too small--it's just the length from straps to the leg opening.
Other than that, they're good bibs and I wish I had gotten a Medium. I was just a bit misled by the suggested sizing.
