How long ago did they change? I have a couple of Royal short sleeves from maybe 2 years ago and they fit nicely. This is sad newsRoyal and Oakley used to make some good loose fit xxl stuff but not any more unfortunately.
On the subject of shorts, my last purchase was a couple of pairs of Endura Humvee shorts. They’re nice, but the jury is out just yet on longevity. They’re much better shorts than my old Fox ones
