I have been using a Gentex HGU56p for abour 7 years now and have not had a worry comfort wise. You just put in the velcro spacer pads to fit your head size, wiggle and adjust as necessary.
I have never had a sore head or neck since the first day I wore it.
I would probably buy another one when the time for repalcement comes.
Good Luck
