3M™ SecureFit™ X5000 is a really great helmet. I use it myself and highly recommend it.
It is a combined helmet with a high degree of protection. Protects both when the material falls on the head and when hitting the head on obstacles, but also when falling and hitting the head on obstacles.
In addition, it is great to wear and is very breathable.
The chin strap has a great fastening system and an adjustable strength of 150 N or 250 N.
