Two designs for your eyeballs today, so I hope you can forgive the lack of shoulder patches on both (at least for now). I present hockey jersey designs for the X-Men and the Sentinels.
For the Mutants I wanted a subtle ‘X’ in the main logo, hence the crossed claws of Wolverine. For the Sentinels I gave a shout-out to the 90’s cartoon intro, where mutant-grabbing cables extruded from the hands.
I doubt either of these could be offered, but I’ve been wrong before.
UPDATE (Feb 14/2017): I just put the finishing touches on a 3rd X-Men design, the Hellfire Club. It is based on the uniforms worn by the hockey program at Harvard.
