I have a large and am 6'0" 185lbs and this jersey is very loose on me. It is also very long for my tastes. Nicely made, but when I put my phone in the middle back pocket it seems to hang and bop around on every bump. But it is a good price for a recreational rider. If you have the makings of a tire around your waist, this would probably be a good jersey. Seems like there is a lot of room there.
