Flylow Firebird or Baker Bibs

I'm on the hunt for some big baggy bibs and I'm looking at the Flylow Firebirds, I know a lot of people are big fans of the baker bibs but the Firebirds are a little cheaper and seem somewhat similar to the baker bibs. In terms of sizing I think id probably buy an XL or XXL, flylow doesn't really have any measurements apart from waist size on them so if anyone has measurements or photos from either bibs it would be appreciated. Does anyone have experience with either of the flylow bibs or recommends any other good baggy bibs?
