You can carry with it naked if you want, it also works with a tux, and everywhere in between.
It adjusts and it also allows you to adjust where you run the gun on your body in a much larger way than something tied to your pants.
It does what it appears to do, I run one, and have a Tier One Aegis Elite, amongst leather holsters and on and on and on... $150 for a holster is nothing, $150 for a toothpick is something.
I have the JM Kydex holster shell in mine, I ran it with another brand originally, it was adjustable retention, wasn't rocket surgery figuring out how to use that either. I went with the JM because it's noted as allowing the gun to ride higher above the faceplate, which it does, though that created another issue for me, though minor.
Wear it with nothing, with gym shorts, in pajamas, work clothes, suit, whatever...
Taking a leak, you can move the gun easy if need be, taking a dump, you can still wear it if you wish, taking a long road trip, you can simply shift everything up so your belly isn't rubbing on things, so your nuts aren't getting crushed so on and so forth with all the issues people talk about with Appendix carry.
It isn't tied to your pants, so you can do a lot with it, you could probably wear the thing like a bandolier even. Better than a belly band, though they are advancing those things as well.
I don't know what else to say, it straight forward does what it notes it does, it is what it appears to be. I can carry my P320 with my 21 round mag in it with this, with my Tier One Aegis Elite I put my 17rd in, the Enigma makes concealing larger rigs easier.
