These undershirts are fantastic! I know it would seem crazy to be so excited about undershirts, but I have had horrible luck getting them to a.) fit and b.) be softer than sandpaper. I had given up on softness and decided it was more important to not have my undershirts riding up all the time. The comfort of these shirts seemed like a bonus! I have tried regular large and XL and they were just baggier, but not longer. If you are under 6' 4", these shirts will consistently (even after being in the dryer) stay below your belt line. Also, I have washed and worn them about ten times and they are still comfortable and still fit well.
