Many westerners go for a hat/cap and headnet in the jungle. I think this is OK if you are not exerting yourself too much. Try it when doing a massively physical activity and the heat combined with humidity quickly makes it impractical. Mosquitoes and flies tend to go for the legs anyway.A different story in the Arctic where high winds and freezing temperatures can quickly give you frostbite on the ear or nose. Even there, when engaged in very physical activity a lighter woolly hat or no hat at all may be possible – depending on temperature.
In the Salar I expect massive swings from night-time temperatures of -20C to day time temperatures of +15C. And so I have selected my head protection accordingly:
Terra Nova Windy Balaclava
This is a windproof, balaclava with a small wired visor. I got one yesterday for £23/$35. My normal cold weather balaclava is an OR Gorilla which has a great detachable face mask. However, I have heard good things about the Windy and I know it has been used on a number of expeditions with good results. It also has a visor (the Gorilla doesn’t), which I think may prove useful in the Salar.
Injinji Desert Hat

This hat has been used extensively in desert stage ultra-marathons like the Marathon des Sables and I have never heard anything bad about it. The newer model has a longer and wider neck cover. My only concern is its performance under high wind as the neck cover does not cinch in the front. I got one for £22/$34.
Is there a single piece of headgear that would protect against wind, cold and the searing sun?
Possibly.
The traditional middle-eastern headscarf called Shemagh was designed to do just that. I have had a shemagh for many years now and its versatility is astounding. I have never used it while doing intense physical activity though so its performance in that respect is unknown to me. I will give it a good test in the Salar and will keep you posted on the results. I wouldn’t be surprised if yet again a traditional approach proves superior to our modern-day technological contrivances.
