Duluth Trading Company sells long t-shirts to hide "plumbers crack"

Be careful though. Both times I've done business with them the item was not as ordered. First time the % of hemp advertised in their hemp shirts was way less than on their website and in their catalog. Second time, the sporran-like thing I ordered was much smaller in all dimensions than they stated on their website and catalog.

Never actually purchased their t-shirts, but they're supposed to be long. They also imply that their other shirts are cut long too...they're not.

Check them out, make your own decision.
