The LS2 airbag helmet has two configurations.
First, semi-airbag. In other words, only two headphones are implanted with airbags.
Second, all-inclusive airbags. That is, the whole lining is an implanted airbag.
No matter what type, the LS2 brand airbag helmet is very simple to use.
You put on your helmet and press the inflation button of the airbag with your finger. Inflate until you are in the right state.
If you feel too inflated and a little tight, there is a deflation button next to the inflation button. When you press the deflate button, the gas will disappear.
