Reviews said to size up with this jacket I’m 6”1 14st 12 ( not 15 ?) and normally a L/XL so I ordered both XL and 2XL they both fitted nice however I opted for the XL as that fitted perfectly,, snug in all the right places, and the service from sportsbikeshop was fantastic arranged collection of the one I didn’t want and was refunded within 5 days after sending it back. Fantastic to deal with
