Bumper Zipper Legality

We are planning on using a bumper with a black base colour, and two cover slips that zip up, using metal zippers, on the side FACING THE INSIDE OF THE ROBOT, and attached to frame with T-Bolts with bolts through them that have O-rings through them(the bolts) as well.

Would this concept be considered legal, and if not, why? Thanks for the feedback!

The black base cover comes to mind as a reason to disallow it. <R07-F>.

I don’t see anything else that would make it illegal, so if you made one color the base and the other the zippered one, you’d probably be fine.

Why not just have a red base with one slip cover?
