My wife is making me some "cooling" clothes out of material from Frogg Toggs (evaporative cooling towels).
I think the best places to have that are:
- Neck (all the way around)
- Lats (along my side)
- My forearms up to just above my elbow (interior of my arm "inside" the elbow more so than the outside)
- Temples would be good but a bit hard to keep cloth there (and it's a very small surface area)
