Familiarity: I've put it through the wringer
Buy it. I hang this cup outside of my backpack filled with energy bars. We will consume the bars on the way up to the mountain. Then, I use the cup for accurate measurement cup when I make backpacking food ( there is markers on the wall of cup once you slip off the cloth). Last, a cup of hot tea which stays hot with the sleeve on is my favorite thing. Best purchase ever.
