I've got a rather big head (I know, I know) and I am delighted with my
special order size 8 Tilley outdoors hat (25 1/8"; 64.5 cm).

I am getting into WW open canoeing and when I did a course none of the
helmets on offer fit me and it was agony to have to wear an L/XL one.

I've scoured the net but my search skills seem to be letting me down. I
keep getting hits of sites advertising XXL life vests but not helmets.
Clearly there seems to be a market for canoeists with normal to small heads
and big guts, but not the other way round!

I wonder whether it all boils down to economics - a XXL helmet wouldn't sell
in millions and maybe would be more involved to manufacture to pass impact
resistance tests etc.

So will I need to buy a Schuberth XXL motorcycle helmet and look like a
right idiot or what else is out there? Football helmets?

I may just have to go back to table tennis ...
