Wore this for the first time after purchase riding from Scotland down to ABR in Warwickshire. 18 degrees in Scotland at 9am, 34 degrees as we rode down. I got the 2XL, which is snug, usually a large in most tops/jackets, 5'11 and 34 waist. However, I have been complimented on it quite a few times and goes really nicely with some smart Roadskin jeans and some more casual looking boots. Slightly disappointing it doesn't come with back protection, but it does clearly call that out in the description.
