collapsable octogon/cage??

A student here at the gym just came back from a seminar over the weekend where apparently there was a collapsable cage. Anyone heard anything about this and or know where to get one?


Btw, the one I'm talking about is way smaller than a normal sized cage.

Thanks for any info.

Are we talking collapsable 'in use' or 'between uses' here?

Between uses I'd imagine.

Actually I don't know, at this point I'm interested in seeing whatever I can cause I ain't found shit on my own yet. lol
