Coaches outfits at the ND game

I really liked the Michigan version of the flag logos at the ND game. I may have had 6 too many afterwards in celebration and forgot to post here. I just recalled today. Does anyone know if a vendor is selling hats with that versions of the M, or is planning to? Also, the three stripes on the Michigan coaches sleaves makes me think, every time, that they have promoted themselve to Seaman, E-3, in the US Navy. Just the way the stripes stand out with the Michigan colors and the way the arms hang on the packets.
