Kuroda's Rebreather

Name: CRBM (Compact Re-Breather Mask)
Description: The device is simple, it is merely a mask that covers the user's mouth, nose, and eyes. As the user exhales, the air is filtered, stored, and fed back to the user. It is a closed system, no air escapes. The device is great for stealth aquatic missions, as no bubbles float to the surface, and situations where one couldn't safely breath.
Level: A
Requirements: N/A
Picture of Equipment:

Spoiler:

This only allows breathing under water? Mine allows for gases as well. Also, fix the image code

It's a re-breather, if you're breathing in a closed system, where the only thing in or out is your own air(Used and recycled), chemicals aren't an issue, besides, that's part of the reason to cover the eyes.

And I fixed the code.

I mean like a poisonous gas or something like that. Mine protects from that

*sigh* It covers the eyes, mouth, nose, and ears, things like tear gas would be useless as a result, about the only chemical thing that would negate the mask is something like mustard gas which attacks the skin.
