Pretty sure that is a carbon fiber sticker wrap to make it look cool, or maybe an actual CF tank, but also to just make it look cool. The people that need low-mag profile items, don't shop through flyers.I am also noticing that all of the fasteners/rings that I can seen seem to be polymer. The O2 cylinder looks like a fiber-wound composite type. I would not be surprised if this was designed for a low magnetic profile ....
I also find it entertaining that if someone is trying to imply "cool and high tech" it's made with polymer. If it's a "cheap piece of junk," it's called plastic. Not directed at you specifically, it's pretty universal, myself included.
There is also some weird photoshop going on, especially with that hand mounted light. Feels very much like it should have been released on April 1st.
