I have yet to find a comfortable helmet for my head shape. I have quite a big head (24"), but the front to back and side to side dimensions aren't the right ratio for any helmet I have ever tried. They are always tight front and back, with a bit of a gap on the sides. So wearing a helmet for any period of time gets quite uncomfortable. I want to get back into riding trials after a few years of doing bugger all and want to avoid the helmet headache.
I much prefer dirt jump/skate style helmets. Unfortunately all my local bike shops predominantly stock roadie and XC helmets, so I am unable to try out a load of different helmets.
Can anyone relate to my head shape issue and have any helmet recommendations?
