Tried on the L/X at the store as this was the only size available. It was just a tiny bit big, so I ordered the S/M paid for shipping thinking this will be a great fit. The hat was a bigger fit that the L/X! Disappointed to say the least, returned the hat and still cost me 7.95 in shipping, lesson learned I know for next time not to order online. Reitmans should expand the online experience -> Order on line pick up at store option.
