My 6'8" husband has an athletic build. His torso is medium length but his arms are long as are his legs. This shirt is not long enough, he lifts his arms , the shirt rises above the navel and the sleeves fall to the elbows. He is so incredibly small it's almost pathetic. We even wondered if it was for men or boys. I took 2 sizes up, I was hoping that it would be longer. Not even close. It's incredibly soft, but that's about it.
