42 inches. I can still put it on but it's too tight with a t-shirt and fleece and the thermal liner zipped in. There's no rips or tears, the leather is still supple and creak free, I fed it last year with muc-off products and it retails at around the 400 notes mark so all in all it's a great piece of gear. All zips and poppers etc are present, correct and operational. There's armour in the shoulders are the length of the forearms and a flexi back protector (a bit flimsy tbh) all built in, the back protector comes out if I recall. If it doesn't sell I'll start training again and regain some fitness and shape....!
