I finally bought an Onyx M-33. It fits. Onyx M or A 33 inflatable
PFDs fit chest size 30"-65". There are two types. The Recreational PFD
devices have a lightweight harness and if you look at the Onyx web site you do not see the sailing harness PFDs at all.
They are sold on a different web site. I called Onyx, they explained it to me, looked it up, and the sizing is the same. The site that sells the sailing harness is a safety equipment
They don't give a waist size because it does not matter. The PFD does not fit that low, in fact, it is supposed to fit above the floating ribs, else you could get impacted by the jerk off hitting the end of the tether.
I decided on the M-33 because I didn't want to risk a brief intentional immersion setting it off accidentally.
It seems to be comfortable and well constructed. The two D rings at the front are always to be used together so that there is no excess stress on the front plastic buckle.
