The core temps before and after the event in both groups were well below the level that would start to imply a danger of heat stroke. This is just BS science in my opinion to help Nike sell more crap...
Since you mentioned performance, I remember seeing that Deena Castor used an ice vest before competition, and I found this (haven't read much of it yet), but: "Conclusions: Wearing an ice vest before
cross-country performance in warm, humid conditions allowed athletes to
start and finish the competition with a lower Tc than did those who did
not wear a vest."
That's exactly what I was thinking as far as a hat... reasonable air flow and lots of shade. How about modding it by spray painting the top white (higher albedo) while painting the bottom of the brim black (facilitate the absorption of heat from the head)?
And the loin cloth is happening, Tuck. Wait 'till you see the pics from Grand Mesa in a few weeks. ;-)

Re: Thermoregulation and Moisture-wicking Materials; A Major Detriment to
I use JZ and Gordo's suggestion now, but not as often as I
should. The major issue I had was relying on drinking more to regulate core
temps. After all, that's the advice typically given. I didn't view overheating
as an overheating issue, rather a hydration/electrolyte issue. Reframing the
problem makes problem-solving much easier as core temp can be managed before
Anyone ever try running with a giant sun hat?

Similar to Gordo's suggestion, Noakes recommends putting
water on the skin (sponging) to help reduce heat stress. I've been
dipping my (moisture wicking) shirt into a stream about halfway through my
runs lately. I don't know if this helps reduce my core temp, but it
certainly feels good.
