The F*ckGear Racer Vest was part of a line coming direct from Mr S in San Francisco and was designed to be played in, but (unlike Rubber) doesn't take a team of people to put on and take off.
 
It's wipe-clean and machine washable too.
 
This vest is marked as a Large an from pit to pit at 18" unworn. I have a 42"/44" chest and it fits me perfectly.
 
Can take more measurements if requested.
 
Mr S no longer make this line, but when they did the RRP was £139.99.
