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

It is actually a 21 oz narrow mouth Nalgene, NOT 16oz. It is also wider than the 16oz wide mouth one.

After years of forking out cash for other upscale brand water bottles for my family of 4, I angrily cleaned out my water bottle cupboard (yes, I have a water bottle cupboard) of broken, missing parts, leaky water bottles that averaged $20 each or more. I glanced over at the counter and there was my husbands trusty Nalgene (looks exactly like this except grey...not much has changed) from 2007. The volume measure on the side is a little worn off but still legible, and the bottle and cap are still trucking along, not leaking, doing their job, after a decade. I realized, those water bottles have been in the dishwasher multiple times per week for 10 years. Hes dropped them many times on various surfaces. He literally dropped one off a cliff while hiking and it survived. Theyve been left in super hot and super cold cars, frozen solid full of water when we found them. The cap is permanently attached, and there are no other parts to lose, so we still have them both intact. They were the only survivors of my purge. His 2 bottles are a plain grey, but now they come in other bright colors so I bought 2 for each family member in their own color choice. This teal with orange was perfect for my daughter. My son got red, and I have purple. What a relief! They are all the same size and shape, easily identifiable, and virtually indestructible. All parts are dishwasher friendly, the kids cant lose straws, caps, plugs, etc. The 16oz size is big enough for me to take on a hike but small enough for my grade school aged kids to handle. There are no fancy drinking mechanisms to learn, clean or break - its just a straight twist off cap that fits nice and tight so you dont worry about throwing it in the bottom of a backpack. And the price - great deal compared to the other bottles Ive been buying! Go for it...you wont be disappointed.

Fun and functional!

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.

Always love a good Nalgene water bottle. It was wrapped in clear plastic which was nice because I knew it had never been used. Great purchase.

Kiddo loves this and uses it everyday. The colors are nice and bright and it has encouraged her to drink water more often. Its fun!

Ive always been super picky about water bottles. The wide openings always hit my nose and spilled water everywhere, but this is a narrow opening so its the perfect size. Its durable, not overly big and intrusive, has a loopy thing to hold on to, and comes in fun colors (cmon people its a factor). Dont hesitate! Good quality for a very fair price!

Nalgene has always been our go to bottles for the outdoors. Really cant go wrong.

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.

I recently returned from a 3-week trip using this water bottle and, without a doubt, it was one of the best items I took with me. It is lightweight, durable, easy to clean and not once did it leak. When I met up with my daughter for this trip I was surprised to see she had also ordered a Nalgene for our trip - the 16-oz wide mouth. We were extremely happy with our purchase of these water bottles and that they are made in the USA was a bonus!
