Without getting close enough to see the UNSC sleeve patch (or the obnoxious "NOOBS GET PWN3D" crest) , I'm not sure this $88 Marc Ecko-designed Halo-themed hoodie really says "Master Chief" to me.

I suppose you can cinch up the hood and create a semi-Spartan helmet visor look with it. Still, this garment seems to be more to be a demonstration of Big Brand A + Big Brand B = $$$$, rather than of street cred or gamer bonafides.
