What’s better than saving space AND the environment!? I used to carry a large stainless steel bottle, but it always felt like wasted space, especially when I had to empty it to pass through security. It was also relatively heavy. My wife found this for me a few years back, and now it comes with me on every trip. I typically clip it to my travel backpack and then toss it in the dishwasher when I return. It has held up well with all the use. I still plan on giving a Vapur bottle a spin since it packs up even smaller, but you can’t go wrong with the Nomader.
