Mont-Bell over-socks. Wear these at mountain huts. Have you ever stepped in spilled tea or water dripping from your backpack? It's cold and the worst. But you'll be fine with these! They're from about 5-6 years ago, so they're a little worn. The main body is thin fleece, and the soles are like thin synthetic leather. They've been home-cleaned. The condition may not be fully conveyed in the images, and there may be differences in color. As I am a private seller, there may be overlooked damage. Please refrain from purchasing if you are looking for a perfect item. Thank you for your understanding of used items.
