We can't say we're not biased when it comes to the Purist Backcountry Water Bottle. The 22-ounce bottle itself is called the Purist, and it's USA-made using a low-density polymer that makes it freezer-friendly and enhances grip. The interior of the bottle, after being molded, gets a 5-nanometer-thick application of silicon dioxide, an inert compound that not only prevents plastic from slowly leeching into the bottle over time, even after washes, but also eliminates that funky water bottle taste we all dread. It's like a pure glass cup in the form of a rough-and-tumble water bottle that happens to look great with The Goat on it, too.
