>>1894160I actually got a full face MTB helmet recently since it was pretty cheap and I wanted to try one out especially for my more dangerous e-skateboarding.
Despite being a bit heavier than most other full face MTB helmets the weight doesn't really bother me.(although I have also worn an even heavier motorcycle helmet before)
It also doesn't limit your field of view with regular glasses, only with goggles which you don't really need but that should be obvious.
So overall it's not a bad option, ironically my biggest problem with it might be that it could draw more unwanted attention to me and my maybe a bit too fast e-bike.
