"We took the SS High Altitude sunscreen with us on a recent 10 day trip to SE Arizona and used it in temps ranging from 30-85 F, and wind, at 5000-9000 feet. We really like it because it goes on smoothly, dries fast, and is not greasy. It provided great sun protection, and we came back without the usual bright red cheeks we get when using other products. We will use it more while spring skiing this month-Will Reitveld, Backpacking Light Order Now
