These shorts are perfect! Ill likely purchase more.  Im always a bit leery about purchasing bottoms online, since Im bottom heavy.  I opted to size up to a large (usually Im a medium) and it worked perfectly.  They were loose and not restricting.  I could have gone with a medium for a more fitted look.

The fabric is pretty nice, not thin at all.  And they are very versatile, can be dressed up/down.

BTW: Im 52/130ish lbs
