Hey Lizzie, that's a great question. I did some investigating and this tube insulator would not be the best for you on Kilimanjaro's summit at night. While doing my research on this subject I found that many folks who stay at the summit overnight find that their tube will freeze and they found it easiest to just pack a couple of water bottles inside their pack, with a thermal sock around them, then wrapped in clothing to keep them insulated against the cold. Since I haven't personally been to Kilimanjaro's summit, I also suggest asking your guide or anyone you know who has successfully done the trek before and kept their water from freezing.
