Thanks for the Mention JAFO, the Flight Caps are a popular choice for the non-aerobatic aviator and look like a normal Baseball cap, so you don't have to paint 'Maverick' on the side of your C152/PA28
They are particularly popular amongst the Rag 'n' Tube pilots as there tends to be a few protuding 'annoyances' to bang your bonce on both getting in and out of the aircraft as well as bouncing around on a turbulent day
Of course there are the Forrest Gump moments when I am glad of the protection, like closing the Canopy on the Rallye when I forget to duck...in fact one customer bought one purely for when he gets his Glider out of its trailor, so it is not just me!
