I'll cut to the chase, I'm fat as hell. LOL 5'-8, currently 299, down from 321.
Down to what matters. I had emailed FHF a few weeks back because I couldn't find any information about how long their straps were on the bino harness. I was a 48 waist in khakis at that point, 58-60 suit coat. Paul responded that day, saying that he advised folks they'd fit up to a 55" chest. The extensions add about 7" per side, so you get about 69" total.
When I got the harness, I tried it unmodified first, straight outta the package. It fit, but was snug. Probably ok with a t-shirt. Adding the extensions makes it fit with breathing room and room to add layers for cooler weather.
Hope that helps the next "round" man looking at FHF gear. I love the products. All seem to be really well made. I think they're going to be perfect for my needs.

I sent my harness off to the local marine canvas company and had them extend the straps. It would have been nice to see these first but the canvas shop did great
