this golf vest is amazing. It’s very well-made. It fits well, I’m a double X and I’m 62 and a slice of pizza from 230 pounds. I just love it and plan to buy more. I believe it’s gonna wear very well, but I’ll let you all know in a month or two after I’ve worn it a couple times and washed it a couple times.
