I’ve never tried it personally due to the fact that it never really gets cold enough to need something like that where I live (Austin, TX). However, it sounds like it would be great for outdoor activities in cold weather like hiking at higher altitudes or cross country skiing. This is assuming, of course, that you’re not allergic to it.
Katie, what has been your experience with it? Or are you skeptical about trying it and, thus, searching for what other people think about the material?
