If you didn't grow up in the desert of the Middle East, you probably think it's crazy to wrap yourself up in cloth to protect yourself from the heat. But this thing really works for me. In the dreadful heat and humidity of Georgia, I have wrapped this shemaugh around my head, face, and neck, and I was truly COOLER and protected from SUNBURN. Apparently, your perspiration is absorbed into the cotton fabric, and the fabric breathes very freely to cool you. I have worn it mowing grass, and was COOL and COMFORTABLE. Incidentally, with my mouth and nose covered, it helped protect me from breathing dust and pollen, too. I recently wore it while I did chainsaw work to clear debris after a tornado. Wore it all day for two straight days. Some people probably thought I was nuts. But it was COOLER, and I didn't get sunburned, either. You can wear it over your mouth and nose, just your mouth, or under your chin. Or even just around your neck. Very versatile. I watched a video on YouTube to learn a couple of ways to tie it on. After some practice, it has become very easy and natural to put on. I have tried those bandanna things that soak up water and swell up with a gel-like substance. Even after taking them from the refrigerator and wearing them around my neck or head, they don't work nearly as well--not even close. BTW--I bought the foliage (no pattern) color, but I assume the other colors/patterns are essentially the same. I highly recommend you try one.
