Balloon-Style Chest Protector for FP?

[SWFLguy]

I used to use a "raft" for baseball and sometimes
men's fast pitch. It was not a baloon filled with air
but a impact absorbing foam material.
I loved it. I'm a big guy 6'3" 275 and I sweat like
a stuck pig with an inside protector. I never had a
problem with it--learned how to wield it w/o any
complications.
And it worked !!!
Since going to an inside protector I've taken numerous
hits and dings to my wrists, elbows, and fingers--
something that never happened with my raft !!
I think it would be a great option for umpires with
injuries or very vulnerable body parts.
Just sayin'
