The Lightrock, a hanging, freestanding double-wall tent, is a lightweight, quick-to-set-up one-person tent, perfect for mountain camping. I've used it for mountain camping about 5 times. I haven't washed or cleaned it. (I don't want to damage the tent with amateur work) I did wipe it down with water, but since my last mountain climb was Mt. Tsubakuro, I think there might be some sand left. The color is a very nice blue-gray, and it's recommended for those who don't want to be like everyone else. Please understand that this is a used item, and no claims or returns are accepted.
