Nations Collection - Limited Edition. Tap into the retro sportswear trend with our Black Diamonds Collection. We dug deep into our archive for this men’s track jacket. Trimmed with logo stripes along the sleeves, our Black Diamonds jacket references our ’70s designs. The three-diamond patch with our moniker enhances the vintage look of this casual style. Finished with a ton sur ton collar and hems plus two handy front pockets, wear yours with jeans and a t-shirt for a post-gym drink.
