It’s a good question. I’m quite disappointed myself. The material they have used is garbage. It’s rough. For some reason the black ones are far worse than the gray. I have a suspicion that Companies send their junk items that should go to an outlet store to Amazon buyers.
These boxer briefs are packaged by Hanes as and sold in a five-pack. Different sellers use different terms when listing things in their own systems. This is all well and good, until inventories get uploaded and Amazon assumes they're different things.
