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.

As Advertised!

Product arrived promptly & well-packaged (shrink wrapped packaged & enclosed inside additional box). Golf vest was received "as advertised" & appears to be of good quality. Vest was fairly priced & is very comfy, lightweight, stylish & wrinkle resistant. Purchased as a gift for my adult son for his future golf adventures. Size/fit will need to be determined by my son when he prepares for his next golf outing. Very pleased with my purchase & will consider additional purchases from seller in the future.
