This is a brand new with all tags lightweight men's golf vest from Zero Restriction. Per the tag, it reads, "Complete freedom of movement, Superior Weather Protection, The Number one outerwear on tour." Labeled a men's size small, but is pretty roomy so it might fit a medium.
Has two big, roomy pockets and button closure at the top. Has a water repellent finish. Size small mens. Perfect condition. Does have the Tradeweb company brand logo embroidered on the back of the vest, although it is barely noticeable. You can zoom in on the pic of the back of the shirt to see it.
