The Nalgene Wide Mouth bottle is one of them. It rides in backpacks, gym bags, tents and office desks all over the world, usually covered in stickers, and it tends to outlast the bag it is carried in. Here is what makes the 32-ounce Wide Mouth the classic Nalgene, which size to get and where to buy one. *Unknowndivide may earn a commission from purchases made through links in this post.* ## What it is The [Nalgene 32oz Wide Mouth Bottle](https://nalgene.com/product/32oz-wide-mouth-sustain/?ref=unknowndivide.com) is a simple, tough, reusable water bottle with a wide opening and a screw-on loop-top cap. Nalgene now makes it from Tritan Renew, a material that is free of bisphenol A (BPA) and bisphenol S (BPS). It is leakproof, dishwasher safe and made in the USA. The numbers are easy to remember. According to Nalgene, the bottle stands 8.25 inches tall, measures 3.5 inches across and weighs 6.25 ounces empty. The cap is 2.5 inches (63 millimeters) in diameter. ## Materials and where it is made Nalgene describes the current Wide Mouth as thoughtfully made from Tritan Renew, and it keeps the bottle free of BPA and BPS so water tastes clean. The bottle is made in the USA, which Nalgene ties to local jobs and fewer emissions. It also comes in a long list of colors on Nalgene's site, from Cerulean and Trout Green to Butter, Mocha and a Clear option, so it is easy to tell your bottle apart from everyone else's at camp. ## Why the wide mouth matters The wide opening is the whole point. Nalgene says it fits most filtration devices, which matters on the trail when you need to filter water straight into the bottle. It also takes ice cubes without a fight, makes it easy to scoop water from a stream, and lets you get a hand or a brush inside to clean it. Powdered drink mixes go in without a funnel too. The cap seals with what Nalgene calls continuous, straight-shouldered semi-buttress threads, which keep the bottle sealed tight. The cap stays attached to the bottle by a loop, so it does not get lost. ## Why it is still worth buying - **It is built to last.** Nalgene says its bottles are made to last a lifetime, and plenty of owners say they have carried the same one for a decade or more. - **It is light.** At 6.25 ounces empty, it is much lighter than an insulated steel bottle of the same size. - **It does not leak.** The threaded cap seals reliably, so it can ride inside a pack next to a laptop. - **It is easy to clean.** It is dishwasher safe, and the wide opening means nothing hides in corners. - **It is endlessly customizable.** Nalgene sells it in dozens of colors and offers accessories like the Easy Sipper insert, replacement caps and bottle sleeves. ## Which size to buy - **32 ounce.** The classic and the one most people should buy. Big enough for a long hike or a full workday. - **16 ounce.** The [16oz Wide Mouth](https://nalgene.com/product/16oz-wide-mouth-sustain/?ref=unknowndivide.com) is the smaller option if you want something lighter for everyday carry. - **Narrow Mouth.** Nalgene also makes Narrow Mouth versions in several sizes, if you prefer a smaller opening. ## Nalgene or insulated steel A Nalgene does not keep drinks hot or cold for hours the way a vacuum bottle does. If you want hot coffee at lunch, the [Stanley Classic Legendary Bottle](https://www.unknowndivide.com/stanley-classic-legendary-bottle/) is the better tool. But for plain water, the Nalgene is lighter, cheaper to replace and easier to clean. Many people own one of each. A Nalgene also pairs nicely with the rest of a simple kit, from the [Opinel No.08](https://www.unknowndivide.com/opinel-no-08-folding-knife/) to the bags in our [best carry-on travel backpacks](https://www.unknowndivide.com/best-carry-on-travel-backpacks/) guide.

Leave the cap off between uses so it dries fully. If you use drink mixes, rinse it soon after to avoid lingering flavors. ## Where to buy Nalgene sells every size and color direct, and the bottle is widely available from outdoor and sporting goods retailers. **Shop the Nalgene Wide Mouth** [32oz Wide Mouth Bottle at Nalgene](https://nalgene.com/product/32oz-wide-mouth-sustain/?ref=unknowndivide.com) [Nalgene 32oz Wide Mouth bottle in blue](https://www.amazon.com/dp/B001NCDE8O?tag=unknowndivi02-20&ref=unknowndivide.com) [Nalgene 16oz Wide Mouth bottle](https://www.amazon.com/dp/B0BMRZG462?tag=unknowndivi02-20&ref=unknowndivide.com) More gear built to last lives in our [everyday carry hub](https://www.unknowndivide.com/everyday-carry/).
