Rated 1 out of 5 by DOCon from Can’t clean well Opening to small to get inside to clean, even with brush

Rated 5 out of 5 by NNBlu from Great bottle for 8th grader I bought this for my son, for school. School rules indicate that they have to have a clear bottle for water. This narrow mouth has been easier for him vs his traditional Nalgene wide mouth bottle . He has been drinking more water with it . So far so Good !

Rated 5 out of 5 by Cynthia from Thirsty Nice water bottle. I really like the small mouth. I use it everyday.

Rated 5 out of 5 by Cool Mom from Great water bottle Nalgene is the best. These are great water bottles for long hikes/athletic events where standard size bottles aren't enough. The narrow mouth means your kids (or you) won't spill water down the front of their shirts. They are a little more of a challenge to clean than their wide mouth sibling but a flexible bottle brush does the trick. Grab this bottle quickly if it is in stock. Supply chain issues have made delivery on these tough. I'm still waiting for 2 more bottles and have been for months.
