Is there such a thing as a “privacy helmet”? [closed]

I have given up the idea of ever talking people out of carrying around surveillance devices or to influence the global society to remove all these surveillance cameras, mics, sensors, etc. I no longer go outdoors at all. This is crippling me for obvious reasons.

In the last few years, I’ve been thinking about possible ways to avoid being tracked. Of course, I don’t have a surveillance unit myself, but that doesn’t help at all since everyone else does, and I cannot destroy all the cameras and mic and sensors without going to prison or worse. I need to somehow cover my face at the very least, although that still won’t help against walking style/body shape/clothes recognition…

Is there such a thing as “privacy helmet” which I can buy and put on my head which not only physically protects my head, but covers my entire head in such a way that I become impossible to identify, and which is comfortable to wear? I’m thinking that on the outside, it just looks like chrome or completely black with no logos or anything on it. Preferably, it should have an advanced cooling system so that it doesn’t become a chore to wear in the summer time, but rather has the added benefit of basically being a portable air conditioner.

Inside, it should either have some kind of one-way glass so that I can look out and see where I’m going (yet nobody can see my eyes/face from the outside), or possibly a digital screen showing a 360 view around me, allowing me to “look behind my back” without turning my head. However, it doesn’t need to be that high-tech, and it would be preferable if this contraption didn’t require any power (battery) for practical and cost reasons. However, it may be necessary for the active cooling and whatnot.

Of course, such a privacy helmet would likely be abused by violent and evil criminals, ruining my chances of buying and using one for privacy alone. (I have zero intentions of abusing this, whether anyone believes it or not.) Maybe it even is illegal to wear such a thing.

Frankly, it surprises me that I have never heard of such a thing. If it exists, it is not well advertised.
