Ahead of his showdown against "The Fiend" Bray Wyatt in a Strap Match for the WWE Universal Championship at this Sunday's WWE Royal Rumble pay-per-view, Daniel Bryan and WWE have partnered up on an eco-friendly t-shirt that reads "YES" on the front and "The Planet's Champion" on the back (see photos above).
