This has to be one of the best purchases I've made. These are perfect for all kind of outdoor scenarios. I bought one off Amazon before I left for a vacation at Lake Powell, man I'm glad I got it. When I first showed up to Lake Powell the winds were ripping at 40-50 mph at the Bullfrog Marina. The blasts of sand in your face, eyes, and mouth was awful. So I pulled out my shemagh, wrapped it around my head and face "SAS" style, and coupled it with a pair of sun glasses (goggles would have been better). Man, I was being envied by fellow vacationers.  For ten bucks you can't go wrong with these, heck buy two or three! There great for the heat and the cold. I'm going to buy my bro one for his birthday because he's a airsoft/paintball guru, and I heard that they're a great addition to have when in battles.
