In this guide
Choose a water bottle around the places it has to fit. With the Nalgene 32oz Wide Mouth that means measuring the side pocket of your bag before anything else. A bottle that ends up carried in one hand every day has failed at the part of the job nobody advertises.
The violet variant was listed at $16.99 when checked. The appeal is how little there is to it: fill, close, drink, wash. Simplicity is worth paying for. An 89mm body and a kilo of water when full are the two things that decide whether you get to enjoy it.
Our verdict
Choose 16oz for a constrained bag with dependable refills, or 32oz for longer ordinary gaps between them. Keep a suitable bottle if one is already in the cupboard.
- A good fit for
- Anyone happy with a plain screw-cap bottle who can carry its filled weight comfortably.
- We would skip it if
- You need a narrow cup-holder fit, one-handed sipping, or hours of temperature retention.
Reasons to consider it
- A wide opening gives direct access for filling and cleaning
- Simple screw-cap operation avoids a complex drinking mechanism
The compromises
- The body may be too wide for a particular holder or pocket
- More capacity means more weight whenever you fill it
What we have not verified: Neither size was tested for leakage, drinking comfort or pocket fit. Published dimension differences are not comparative performance.
The things in this guide
A closer look at the products, who they may suit, and what to check before buying.
32oz Wide Mouth Bottle
Prefer it when a longer ordinary gap between refills makes extra volume useful.
Before you buy: Check the wider body against the packed bag; extra capacity need not be filled automatically.

16oz Wide Mouth Bottle
Prefer it when refills are easy and a smaller bottle fits the bag you actually carry.
Before you buy: Less reserve leaves less flexibility when the schedule changes.
Price checked September 10, 2026. Retailer prices can change.The water weighs much more than the empty bottle
Nalgene lists an 89mm body diameter, 21cm height, and approximately 177g empty weight. At 32 US fluid ounces, the water alone is roughly 946g, bringing a fully filled bottle to about 1.12kg. That is our calculation from the published capacity, not a measured sample weight.
Count the hours between reliable taps on your ordinary day. Carrying a liter is sensible on a trail and pointless in an office with a water cooler. Size it to the route, not to the idea that more capacity is better value.
A wide mouth favors a deliberate pause
The screw cap and open rim suit a pause: at a desk, on a bench, standing still. Anyone who needs a mouthful while driving or cycling should be comparing bite valves and flip lids instead.
Rehearse it with a bottle from the cupboard. Where does the cap go, how far do you have to tilt, is there anywhere to set it down. No spill comparison was run here, but the handling sequence is obvious enough to shop by.
Keep the material and temperature expectations realistic
The current model uses Tritan Renew, described by Nalgene as dishwasher safe and leakproof. The second word is the manufacturer's, not a test result from here. Check the cap threads and the seal periodically; a familiar brand name is not an inspection.
Buy it to carry water. Cold drinks that stay cold need a vacuum flask, and no amount of recycled content justifies replacing a bottle that still works. Keeping the one you own is the cheaper and greener answer.
Choose one that travels reliably, then keep using it
For a first purchase, check the actual pocket opening and whether the bottle remains accessible when the bag is full. A measurement taken from an empty flexible pocket may be misleading. If trying in person, use the bag and load you normally carry rather than a showroom approximation.
Favorable when the size, the opening and the cleaning all suit you. Go smaller or narrower if the bottle keeps getting left on the counter. The aim is one bottle that travels, not a shelf of them for routines you do not have yet.
The larger bottle takes the space even when partly filled
Nalgene lists body diameters of 70mm for the 16oz model and 89mm for the 32oz model. Empty weights are 88.5g and 177.25g respectively. The larger bottle remains the larger physical object even when carrying a smaller amount.
In a tight side pocket that difference decides everything. In a roomy backpack it disappears, because a large bottle filled halfway carries the same water as a small one filled to the top. Buy the smaller bottle when the container is the packing problem, not when the water is.
