BeautyflierNeoprene Water Bottle Sleeve Insulator Cooler, Compatible with Nalgene Water Bottle 32 OZ, with Adjustable Shoulder Strap for Hydro Flask Wide Mouth Bottle 32oz, etc. (Beige)

Fits my mason jars better than my mason jar neoprene sleeves, perfectly. Can lid the jar or use it without the lid and neoprene sits just below or just above the glass either way just fine. For some reason i thought this included a regular handle too but it does not. I like the handles because my hand has gotten weak but my misunderstanding. Keeping anyway because it fits so well and i like the strap on occasion. I read some thought the strap was too short. I'm 5'1" and at full length the cup hits below my hip. Its plenty long

This nalgene bottle holder would be fantastic if not for one serious flaw. After just six days on a canoe trip, the sleeve material around the two side ring attachments on both sides of the bottle was torn. I purchased two of these sleeves and both of them had the same problem. The bottles were hung by carabiners from the outside straps of the dry bags while portaging and would be similar to attachment to backpacks while hiking. It is a great product if you are transporting empty 1 liter nalgene bottles, but the neoprene sleeve material around the stiched side rings can not support nalgene bottles for extended active portaging/ hiking trips. I don't think they would last more than 3 or 4 weeks before full failure.

This is a great cover for an add of color to my water bottle. It doesn't keep it cooler longer than wrapping a paper towel around it would.I'd buy in different colors for a cute visual, and that's about it.

Keeps my Nalgene from sweating and keeps the water cold a bit longer.

Doesn't insulate much, but prevents condensation from leaking off of the bottle.

The media could not be loaded. This doesn't even come close to fitting a 32 ounce bottle. Now I'll have to order another for my mother.
