Looks to me like a utilikilt knockoff.
I don't see the similarity at all. The Tactical Duty Kilt is OBVIOUSLY more versatile than the Utilikilt, which appears to be a standard everyday kilt. No movable ammo pockets, no reinforced pocket corners... pretty darn useless. But the TDK, man, what a kilt!
