Let’s see how many water bottle brands I can still recite from memory: Hydro Flask, Nalgene, Platypus, Snow Peak, Klean Kanteen, Stanley, Yeti, Katadyn, LifeStraw, CamelBak... But ask me which one of these brands made the best water bottle, and I’d be hard-pressed to answer, because they all had issues. What I learned from the year I spent hawking water bottles is that there’s no such thing as a perfect water bottle. The is the most thoughtfully designed water bottle I’ve ever used. Yes, it keeps beverages cold for 24 hours; yes, it’s triple-vacuum-sealed, and BPA-free, and fits a cup holder, and has a lifetime warranty, yada, yada, yada.
