Gear Review of the Nalgene 32 oz Wide Mouth

Revelation: The Moment I Knew

I’ve never been a big backcountry water bottle carrier. I use hydration reservoirs as much as possible for their convenience and tendency to encourage water consumption. So, when I received a water bottle to test, I begrudgingly took it with me to Montana to use during a four-week stint interning with the Bob Marshall Wilderness Foundation near Glacier National Park. I spent these weeks hiking and rafting into remote areas to pull, survey, and map invasive weed infestations in partnership with the Forest Service.

On each foray into the wild the Nalgene 32oz Wide Mouth bottle served me well. The Nalgene Wide Mouth is the industry standard for water bottles. The adapter hose from Katadyn Hiker Pro water filter I was also testing mated perfectly with the bottle and made filling from streams and lakes — and even the deck of our river raft — spill-free and fast.


The 32 oz Wide Mouth is a classic, which means other gear is built to be used with it.

One of the main reasons I’ve always loathed water bottles while backpacking is the accessibility while walking. Every backpack I’ve used has horrible water bottle pockets that reduce me to wild flailing when attempting to pull out my bottle. When using the Gregory Baltoro 65’s water bottle pocket, this was no longer an issue. Having a backpack that encourages water bottle usage through good pocket placement is critical in the backcountry and allowed me to fall in love with the classic design of the Nalgene.


Many backpack pockets are made to specifically fit the Nalgene 32 oz Wide Mouth.

The convenience of drinking out of a familiar water bottle instead of a hose while on the trail gave me a strange sense of comfort that I didn’t even know I was missing. This was the moment I understood why the Nalgene is found on practically every trail on earth.

Digging Deeper


Nalgene has roots in the scientific industry, and you can tell by its truly leakproof lid. Even when inverted and during heavy gains and losses of elevation, nary a drop left the bottle to soak my goods.


The lid is one we’re all familiar with. It screws on and it is attached.


I’ve literally dropped my Nalgene bottles from two-story buildings. They never showed  more than a scuff. To test the durability of the Nalgene 32oz Wide Mouth, I filled it and slammed it on asphalt. I launched it off a cliff above the Middle Fork of the Flathead River. I dropped river stones on it. I think you get the picture: this thing is almost indestructible.

Form Factor

The Nalgene Wide Mouth bottle is the shape and size most manufacturers spec their bottle-carrying products to — a benefit of being the industry standard. I never had a problem sneaking its slick, rounded form into full packs or pulling it easily out of the outer pockets of a trekking pack. My hands are medium-large sized and have no problem gripping the bottle even when wet. Someone with small hands may have more difficulty as it is a wide bottle.


Expression aside, I love drinking from this thing.


The Nalgene 32oz Wide Mouth does require some finesse when drinking to avoid losing most of your treated water to your shirt. But, it wasn’t a deal breaker. The wide mouth makes filling with ice and cleaning after use really simple. Also, the Tritan plastic doesn’t lend the water a flavor. A huge plus when drinking fresh mountain spring water.

For those who need a Nalgene but can’t handle a wide mouth, there’s the Narrow Mouth version.


My only grievance with the Nalgene Wide Mouth is the stink factor. Nalgenes in particular have the tendency to develop a funky smell around the lid threads. I don’t know if it’s because the coarseness of the thread traps water or if the super seal traps heat and mildew, but I’ve noticed it for years. As long as you’re using the bottle frequently and refilling with fresh water daily, it’s not a big deal. But, I’ve stashed a full bottle in my car for after a multi-day hike and had to plug my nose to down the water within.

Final Word

The Nalgene 32oz Wide Mouth is a true classic among water bottles, about as classic as a water bottle can be. If you don’t lose it, yours will be with you for many years and miles to come. And, make sure to grab a sticker to make it extra cool…
