Actually, using your t-shirt size works remarkably well.
And we mean your "adult men's t-shirt" size
This is a top-of-the-line short-sleeved rash guard. These shirts are designed specifically for no-gi/vale tudo grappling and warm up training. They are also great worn under your gi!
These are blank rash guards except for a small (about 2 1/2") "Piranha Gear" oval below the back of the neck.
Tight fitting, elasticized, stay-fit edge on cuff and at bottom hem of shirt. Made of a durable Lycra blend fabric (spandex).
These have nice LONG torso's so they don't ride up on your stomach while you're moving around.
Please note: If you have REALLY BIG ARMS, you probably want to go up one size (big like your t-shirt sleeves are TIGHT). While the cuff on the sleeve is great, it does mean you might not be comfortable if everyone else is always jealous about how big your arms are.
And yes, in case you're wondering, we sell LOTS of these to surfers and SCUBA divers for under their wetsuits...
