Both DLX and NHS tee's have a similar fit to Gildan shirts or Hane's beefy tees. The more premium type shirts that RVCA, Volcom, Altamont, Brixton, etc. make are usually some type of tri-blend tee's but they're usually more expensive because of the quality. Personally, I've always liked the premium quality better because it doesn't turn into a crop-top after a few washes.
