We can't even know the sizing of jibberish anymore. The fit changes for year to year. This winter their stuff was not that bit but the summer line is very tall. So if you get something from the summer line, get it in M or L depending on how big you want it.
na dogg, i went to jiberish in denver and bought 2 hoodies in 4xl. they dont advertise it, but they do sell it. they usually save the 4xl for the pros. but 3xl was tiny, so i asked the dude if there was any bigger and he was like "ye weve got 4x for the pros, we dont usually advertise it but yea you can get it if you want." so i got 4xl
