Iron Man suit I have never seen before...

[Radigast]

Is there a designation for this variant or is this not an official suit and just a concept?
I see that it was for a variant cover of Iron Man #18.

Here's the issue they're talking about:

It's just a variant cover, nothing "official". Looks kinda like the Superior Iron Man armor though.

Thank you very much for the info msleeper! It definitely had some interesting looking features on it.
