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.

Great vest

Color: Dark Grey, Size: X-Large

This lil vest is awesome. A little thicker than I expected but perfect for my cool office. Looks like it cost twice as much. I had my company info put on it and looks like it cost 150.
