Nalgene Sustain Tritan BPA-Free Water Bottle Made with Material Derived from 50% Plastic Waste, 16 OZ, Narrow Mouth

Fits perfectly in my bag! Holding and carrying big heavy bottles is inconvenient. My only complaint is that it’s not insulated to stay cold but I’ll live

After getting a Nalgene bottle a few years back, I will never get another brand. They never leak and have a variety of options for the opening to sip how you want. This little guy is absolutely adorable and while not ideal (in my opinion) for water consumption if you dont have a faucet anywhere to fill it up every hour (16oz is very small) it worked great for my electrolyte mix. For a while I was using my regular water bottle for my electrolyte mix and then refilling which gave me a faint taste of the powder I used which was unpleasant. Now I just bring this guy around with me too. Sturdy and has been through many beating without cracking. Great for hiking or other outdoor activities.

Needed for SOs powder drink mix that is 16oz. We have several larger bottles and use them daily, but needed a small one for this drink mix purpose. Only issue is the plastic packaging let residue on the bottle that will not come off, seems like it got really hot and fused to the outside. Not a deal breaker, but annoying still. 4 stars because of the forever plastic stuck to it!

Perfect size, well built, and Nalgene just knows how to make the perfect bottle opening—it just fits your lips perfectly and comfortably with no leaks. 5 stars!

I purchased this for my child in kindergarten. We have only used straw type water bottles prior to purchasing this, so I wasn’t sure how this type of water bottle would work. It has been great. My child can easily open/close it with no spills. They can also fill it on their own, compared to the stainless water bottles (they can’t get the lid off on their own). And it is the perfect size for their backpack. I would definitely recommend.

This is such a sturdy yet lightweight, compact, and ergonomic water bottle! I feel like Ive been missing out all my life. Its so easy to grab, throw it into my bag or backpack, and be out and about, or even just absent mindedly carry around the house with me. I really needed something lightweight as I cant/ dont feel like taking my heavier or bulkier water bottles, but then end up thirsty or tempted into getting a disposable plastic water bottle instead. I love the attached cap thats easy to screw off and on, as well as clean thoroughly.

I had a yellow one that my action figure prop--I always had it with me--and which I lost once on a trip to Portland. I replaced it with this, and its good, but one thing to be aware of is that it will leak for a moment after putting the lid on. I always have to be careful when putting it into my bag so my papers dont get wet. Thats kind of annoying, but since I am always careful with it now it works well because its small and portable. I also love this color and the other color options available. Perfect for travel or going to the gym! Or for every day use, really.

I have the 32oz but wanted something smaller for the office/classroom. This 16oz is perfect and is stylish too

I have the lemon/orange slice decor one and I just purchased this pineapple pattern one. They are very very sturdy, lid is absoluely leak-proof and you can carry it around with your finger on the ring. You also feel comfortable that it wont open up in your work bag. It makes drinking water FUN.

We are a long-time consumer of Nalgene products because of their amazing customer service. Very few of our purchases have broken over time, but those that have cracked are always replaced because of the lifetime guarantee. This size was purchased for our daughter and is an excellent size for her. The narrow mouth makes it less prone to spill compared to the wide-mouth bottles. It is still easy to clean. We will certainly purchase more.
