This Belgian military-issue steel helmet is likely a modern version of the traditional steel helmet. It is designed to protect the head from impact and injury, and it may also provide some protection against bullets and other projectiles*.

The helmets come in used condition and we have two variations of them in this listing. 

*These are used military surplus helmets and are not intended for protective use.
