Havelocks were originally created for military use, but they are also used to decorate other helmets, this particular havelock was designed to decorate kids riding helmets.
However, because it was a kids helmet cover it was cheap and allowed me to take a few photos and explain a bit about a havelock.
It also came with pompons which you could press stud onto the top.
Not sure if I could argue a case for use of pompoms for military use
