Any outdoorsy person knows that choosing the right water bottle for the adventure matters. I personally have an entire cabinet dedicated to all sorts of bottles, thermoses and the like. Google search “best water bottle”and you’ll get hits from thousands of websites including Outside Online, Outdoor Gear Lab, Popular Mechanics and so many more!
The problem is none of the reviews that I’ve found actually quantify “best” in way in the way I was looking for. Being that my day job is a test engineer at a certified lab I decided to take on the challenge.
For our Denali trip I decided that the most important quality I was “how long will my bottle keep boiling water hot?” Denali is a cold place and I wanted to know that my water wouldn’t freeze instantly and that I could warm my belly with hot tea and electrolytes hours into each day’s climb.
