This bottle is absolutely perfect for just about anything you need tho keep cold, but excels at keeping carbonated drinks fizzy! Most water bottles are constructed for non-carbonated drinks, and they will foam over, but this one has a pressure release, so that you can put cokes or adult carbonated drinks in with no issues. Perfect when I want some cold caffeine while I’m driving, but don’t want to stop at the convenience store. Definitely a winner!
