Some muscle relaxant called Bionic Cooling Liquid


And then some ingredients:

Latex Mask
Rubbery Resin
Psudocoelomatic Membrane from a Molock
Bladder of Abyssal Shark Bile
And two Arctic Leet Eyeball's

Used to protect yourself against the insane glare of the Penumbra Sun. Without it, any combat or hostile nano execution is almost impossible.

It also adds that little touch of extra cold protection, (through an artificial skin made by nano-bots) to avoid the biting cold of the areas.
