>Many people who've worn them say that helmets are very hot and fatiguing.
I've seen a figure for 40% of the heat from a human is shed from the
head. That might be in clothes, and include the large amount of heat shed
by breathing, so an open face helm might make a big difference.
Having worn several styles of helm for hours on end, I'd say that
they are not too hard to carry (but I lift all the weights on the Nautilus
neck machine) but do interfere with heat shedding. When I am in
good shape, I can jog and fight for hours in 30 degree (86 F)
uh oh more later must go
