I'm 6'2" 205 lbs. I got the XL, and XXL would have been better. I'm going to keep it because if I reach my goal of 195 it will probably fit. In a nut shell it fits very tight so maybe order a size up unless you want a skin tight fit. It seems to be very nice quality.
I have to be to work at 6am and I've used these gloves twice now on my 8 mile commute to work. At 6am it's generally been in the mid-low 20's here in Reno and my hands got cold at first then about the 4 mile mark they warmed up and I arrived to work with toasty hands. Pretty impressive for the low bulk of these gloves.
