Bib is for those a little shorter!

I returned this product before using it

Beautifully made...fantastic construction....Castelli is my favorite. The odd thing though with this one is the shoulder strap length. I'm 6'1" and wear an XXL in Castelli because they run small. I own an older Castelli bib in the same size. Fit in the waist, crouch...perfection. HOWEVER, when I tried to pull the straps over my shoulders, they were so unbelievably tight that I swear they would have ripped out of the bottom after some use. Not an inexpensive garment so I decided to return it. I'm sure I'll find something else from the website soon.

Super Tight; Size Up

I've used it once or twice and have initial impressions

Medium fits very snug, especially in the legs. I have larger than average legs for my build so I am taking that into account (59.7cm/23.5in). Since this product is billed as aero it will run tighter anyway. Despite the snugness, the bibs still fit without stressing the seams. If you buy your size instead of one up they will fit like a skinsuit, which is fine if you're okay with that. Personally for me, I feel if I went a size up the straps would sag on the shoulders.

Usual one size up for Castelli

I've used it once or twice and have initial impressions

5'8" at 161 lbs. Purchased size L. Happy with the fit. It's snug without struggling to get it on.
