The terms "Nalgene" and "water bottle" are often used as synonyms, reflecting on this bottle's continuing popularity over the last decade and more. A time-tested classic, it is as good as plastic gets for most folks getting active in the outdoors. It's simple, durable, inexpensive, and versatile. Given its high performance and affordable price tag, it earned our Best Buy Award. Despite changes in the materials used to manufacture the bottle and cap (making it BPA-free), the basic design of the Wide Mouth has remained unchanged. As they say, if it ain't broke, don't fix it. This 32-ounce bottle is light and durable, making it a great choice for a multitude of outdoor ventures. It's easy to clean and doesn't impart any funky plastic taste on its contents. It can even double as a measuring cup. It is so light and easy to use, we even found ourselves carrying it around town, though it really shines as an outdoor adventure bottle.
The 32 oz Nalgene is the most versatile plastic bottle we tested. It placed well across the board in our scoring metrics, especially in taste and ease of cleaning. It was also the lightest rigid plastic bottle when factoring in its volume (0.20 ounces per fluid ounce). It has a wide mouth (2.25 inches), which is also great when collecting and filtering water from mountain streams. We found this bottle useful in many ways, and are glad that Nalgene has maintained its low price ($11) over the years. Read on to see how our Best Buy Award winner tallied in the individual metrics.
If 32 oz isn't enough for you, this design might still be for you. The Nalgene 48 oz costs only a dollar more while providing 16 more ounces of volume to keep you hydrated all day.
