Ok, so I bout a jacket before from another seller, n it's hard to size depending on ya depth of knowledge on sizing jackets....but I messed up the first time buying my size I feel comfortable in in shirts (xxxl/3x) but after reading the charts a few times n checking reviews on this one, I decided to go a few up, bought the 5xl n it fits perfectly* so my advice, go a size or 2 up, oh, and the jacket is legit* n hella tough, definitely a real biker jacket 💯
