Size L - is a small M you need to order 3 sizes above L = 2...3XL
Good product for the price, 5xl = xl in Canada. It takes a few hours for the buttons to work as they have been compressed into the vacuum bag.
The quality of the buttons aren't great, at first they weren't working at all but after squeezing on the control panel from the sides a few minutes the buttons eventually unlatched and started working somewhat (though the tactile clicks don't seem to be actual button presses?). If you have trouble getting yours to work then be patient and try squeezing it from the sides in various patterns. The buttons are probably supposed to be behind the lights in the panel but on mine they've slipped downwards. I haven't tested it outside yet but the heating seems to work just fine.
Good product thanks
