If the fabric is Kevlar or some bullet-stopping fabric, it may, for the small physical coverage it affords, chance to prevent a brain injury from small arms fire or a stray piece of fine small shrapnel.
Or even if the skull is fractured, the fabric may still prevent the projectile from penetrating brain tissue.
The camouflage color is good of course.
Other than that, it’s a hat to doff for the ladies or throw where you feel at home or toss in the ring for a fight.
And keep track of it and don’t lose it.
