Compared to completely helmets this offers the advantage that it consists of a front part with the mask and a rear portion of the helmet itself ... so actually as Darth Vader in the movie also. The two halves are fixed with a Velcro strap to each other. This keeps very well and also people with larger size heads can order this helmet with no qualms !. The durability is also good ... a lot of hard plastic holds.
The only drawback: the vision visor ... with my helmet, the viewing slots complete with undulating transparent plastic parts ... As a result, a slightly distorted view results easily on longer distances ... 10m + ... but at shorter distance. In this sense, only 4 out of 5 stars ... but otherwise only recommendable product.
