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

It is not easy to drink from or refill. The top is held on by a loop. Both must be held for clearance to take a drink.

I wanted a water bottle that was not huge. This one holds 16 + OZ and is easy to carry.

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

I bought this for my 3 year old. His older brother was about that age when he got his. The narrow mouth is great because 3-year-olds drink like monsters. It’s small size is still manageable for him to lug around... Lord knows I’m done holding on to his stuff. Also, the small size is good so when he takes it to bed, his minuscule bladder won’t erupt causing a flood for me or his mother to deal with. Last, the cap will home those fine motor skills of his tiny, tiny fingers. More so than his nose picking, maybe.

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!

I lost both my small Nalgene bottles and needed a new one. Was happy to come across this new design with small opening as Im a total slob when it comes to liquids and somehow always manage to spill all over myself. This smaller opening is for clumsy, messy people like me who need a bit more control with the bottle sipping. The bottle seems a bit wider but does fit snuggly in my backpack side pocket. Plus the orange color is gorgeous and makes it easy to keep track of! As far as cleaning goes, I hand wash regularly and fill with baking soda to clean/disinfect, shaking vigorously and letting it stand for an hour or so or overnight.

The 16oz size is just right for my needs, not too big or small. The loop on the cap makes a nice carrying strap. I like the smaller neck for drinking out of the bottle, but it’s not as easy to clean as my larger wide mouth Nalgene 32oz. I don’t like most of the color schemes offered and wanted a clear bottle but settled for the cerulean blue one. Another thing I don’t like is the diameter - it doesn’t fit into standard vehicle cup holders. I can wedge it into the upper end on mine, but it’s not secure.

Great bottle for my 11 year old at school. Doesnt leak or spill and fits perfectly on the side of his bookbag. Its a little awkward to clean with the smaller mouth but its still doable. Would repurchase

The new sustain aspect is a big sell. My husband works for the company Nalgene gets there plastic from Eastman Chemical. The way they are molecularly recycling plastic that will never have a end use is pretty ingenious. Check out Eastman Chemical molecular recycling.

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.
