The Nalgene Wide Mouth is made of BPA-free Tritan copolyester -- a material that's used widely for rigid water bottles and found to be very strong and durable. Otherwise, the Wide Mouth is a no-frills, straightforward beverage container. The screw top is attached to the bottle, which allows for easy carrying and prevents users from losing the lid. As its name suggests, the opening of the Wide Mouth is very large, eliciting both pros and cons from users. For sippers who like to add ice to their beverages, the wide mouth is a necessity. On the other hand, some reviewers say the wide opening makes it easy to spill on yourself as you drink.
Because Nalgene is one of the better-known reusable bottle makers, this bottle gets quite a few reviews. The best ones come from Good Housekeeping, which reviews 32 bottles and details its testing criteria, and Time magazine. HuffingtonPost.com includes the entire Nalgene Choice line in its roundup, and user reviews from Amazon.com are especially helpful.
1. Good Housekeeping
Good Housekeeping tests 32 reusable water bottles that claim to be BPA-free. Each bottle is subjected to stability, leak and drop tests, and a panel of testers evaluates the bottles for comfort, ease of use and appearance. The water bottles that claim to be dishwasher-safe are also run through 28 dishwasher cycles. The Nalgene Wide Mouth comes out in the middle of the pack, neither as a favorite nor a loser. The cons of the Wide Mouth focused on functionality and preference (size, weight and more), but the Good Housekeeping review doesn't reveal any issues with structural soundness.

2. Time magazine
Time magazine picks the five most eco-friendly water bottles, and the review includes information on durability and reliability. The review of the Nalgene Wide Mouth is generally positive, with reviewer Hilary Hylton stating that the bottle is large enough to satisfy for a full day. Her complaints are the same as many reviewers: The bottle's large mouth makes spilling almost inevitable.

HuffingtonPost.com provides an array of reusable bottle favorites -- though Armstrong doesn't clarify exactly how the bottles were chosen -- then readers have the option to rate them on a scale of 1 to 10. While most other bottles listed are a specific model, HuffingtonPost.com selects the entire Nalgene Choice line. This makes it difficult to tell whether readers' average low score of 5.6 applies to the Wide Mouth specifically.
