Hey Jay,
Yeah I was looking at your thread the other day trying to find some pointers on the flight suit and made note of having to buy a size up and the post here about breathing all the way in when taking measurements...hence my flexing the chest to allow some tolerance.
I'm going to try a 44R going by your advice as well as RuBain's size chart and the one you posted on page 11. I'll be tucking the legs into the boot so It's more for the sleeve length but a 44R gives you 23 1/4 so that should be fine if I'm 22 1/2. We have a couple of camping/disposal stores here but their stock if VERY limited, only a few jackets, webbing ect.. no flight suits.
I've started looking on evilbay for 44R to see what's out there, a few are available but shipping ranges from $35 up to $55 so I'm waiting to hear back from a couple of sellers to see if they have cheaper shipping options.
Like you said, worst case, I have to buy a larger size they're no good...but if I get stuck $70 out of pocket, it's still a hell of a lot cheaper than some of my other prop failures.
Oh and your answer was just what I was looking for
It helped just to have someone else that has dealt with this give a second opinion which I greatly appreciate Jay.
Regards dan
