I had read so get Alien helmet from my employer, but neither really fit and had to be readjusted repeatedly through the entire belt history.
Thus, a new was needed.
This helmet looks in my opinion, very good, also sits well and lack STrippoen and ligaments to adjust to fit always. He should protect my opinion the mind better.
He is even contrary to expectations, very airy and even something rainproof.
I can only recommend this helmet, my health was certainly worth it.
