Pittsburgh Penguins "RoboPen" Adidas Reverse Retro 2.0. Authentic, Brand New With Tags.
When looking for an authentic NHL Adidas jersey, look at the stitching on the collar. The stitching should run underneath the lettering/sizing on the collar tag, not through it. It should be sizable and well stitched.
Beware of flimsy or small patches. The NHL tag should reflect holographic and read NHL/LNH depending on the angle. For more details of verifying authentics.
