Used Olympia Jacket. This is not the ¾ length AST but rather the shorter version of the AST jacket that comes to your belt line. It is a 4XL and with the liner fits a little more snuggly than that. I am 6’1” with a 52 inch chest and this fit me when I was at 295 with a 54 inch chest. It still fits me but I weigh less. Vents on the arms and chest. Never down. Elbow, shoulder and back protection. It will come with the Olympia stand-alone liner. Pretty nice jacket. Still pretty reflective. I need to clear out the closet, I am told, so $50.00, plus shipping from Eureka, CA.
