it's not the same jacket, according to a thread I finally found there is a third colour in actual black, aside from the grey and blue. the pure black one has black buttons while the grey and indigo versions have brown buttons. apparently black is the rarer limited edition version. that's what I gather from this thread
I'm 6', I think this might fit me as they run small but I've never really worn W+H so I'm not completely confident yet.
