Worn just 1 season during my cross country trip and never used since. Size 46 with adjustable strap on the back (see photo). For reference, I'm 6 foot, 200lbs muscular build with a flat stomach (see photos). I've had quite a few larger guys come by to, unsuccessfully, try it on so If you're larger than this ... it won't fit. Vest is in good condition. Price is good because it may need a good cleaning since it's been stored for years. Cleaning basement... see my other ads.
