I love my Nalgene! I've had mine for well over three years and it is just as dependable as ever. Though it's dishwasher safe, I prefer to hand-wash mine, since I often wear lip balm that is hard for my dishwasher to remove. I love that I can bring an entire liter of water with me wherever I go - it's extremely convenient to toss in my stroller for the whole family to drink from when we go for walks. I don't need any other bottle!

This mouth style is the best type of Nalgene. East to drink, not as easy to clean. But stick with water and it will be fine. Very happy to throw in my hiking bag.
