We just printed some Nike performance long sleeves that were the same. They were black, but if you held them up, you could see right through them. Printed a 2/c on the front and 1/c on the back. Low bleed poly white and a top reg plastisol kelly. You could see the imprint on the inside of the shirt but they turned out looking just fine.
But yes, like everyone else so far, Id run a test. We did.
