These are perfect for travel for travel because they never leak and are really tough. I've used Nalgene bottles for years and they have been unbreakable and never leak, unless I don't close the lid. Just check the sizes to make sure you are getting what you want. I ordered a much eager brand elsewhere. They looked similar but leaked and seemed flimsy. I have had some Nalgenes for 20 yrs.
