I'm a little unusual in my build. Only 5'11", 190lbs. Not fat, but a little thick. Waist is a 32", with a 44" chest. The reason behind the measurements, is that it is difficult to find bibs that fit right. The pair of Izumi Escape Quest, fit perfectly. Comfortable to ride in, with chaffing. A really excellent fit.
What more could you ask for in a cycling bib. I train mostly on Zwift, but I have used this bib on some longer rides outside. I'm 5'9 and 175lbs and a large fits me perfectly.
Overall product is pretty good especially for the price. Light weight does not eat out too much. Chamois is a little cheap but what can you expect in this price. Would recommend for the rides but not for long distances.
This is a great bib. It may not be flashy. It's not a tight race fit. There's no fancy market-speak chamois or a 20 panel design. But it's still quite comfortable and will last. I've been through lots of commuting, plenty of centuries (including a couple doubles) and no issues.
The only complaint I have is that it can get pretty warm in the summer. It has more than usual coverage, especially in the back - but that's just a tradeoff.
I own several Pearl Izumi bib shorts and have been using them for 20+ years . These don't make the grade. I purchased the same size (L) I wear with the other Pearl Izumi shorts and these shorts fell A LOT smaller and tighter. The material isn't especially stretchy like the other bibs. As others mentioned, the chamois is also problematic. The shorts are also really short and tend to ride up and bunch while riding which causes problems with rubbing. I've tried to wear these shorts twice and can't get past how odd they feel. Sadly, they are going in the trash since I can't send them back. Save your money and buy a more expensive, but useable pair.
