When the Islanders move to Brooklyn next year, there are rumours that they will have a new third jersey to share an identity with all other professional Brooklyn teams. For the concept I took the Brooklyn Nets (NBA) collar striping and made it into the striping. I kept the font of the Islanders previous black third jersey.
Here is the jersey photoshopped onto John Tavares.
And just for fun I created this full uniform concept (template can be found here).
