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

I looked for a long time for a water bottle insulating sleeve but most everything was not really all that great or the size would not work on my Contigo 18-20 oz bottle. Finally, I found this sleeve that had the measurements to fit the aforementioned Contigo bottle. As we so many things online, I was a little apprehensive on whether it would fit not only the height but also the girth around the bottle specially since the particular one I have is narrower at the bottom but wider at the top. It turned out to be a perfect fit. Better yet it actually does a true insulating job on keeping the water cold. I usually walk around 1.75 hours or 11 - 12k steps in the mornings In sunny and balmy Florida. The real test is that the water is not just cold but there is still ice in the bottle at the end of my walks. I dislike warm water from any container, with this sleeve I do not have any such issues. The sleeve comes with a sling which truth be told, it is not very useful, the Contigo bottle has a built-in 2 finger plastic loop which is how I carry the bottle. BTW, the bag in no way interferes with the plastic loop when opening the flip top to drink from the bottle. Yes, I am very happy with this insulator bag, it is well made and appears it will last for a good while.

This turned out to be a hidden gem. Easy to clean and the attachments are beefy enough for hiking/backpacking. Keeps my water cool until I need a refill.

I got this for my boyfriend who works at a GM plant. It keeps his water bottle from sweating and the strap is perfect for hanging it up in his work area. He also likes the strap because he can hook it on his cooler and on his tool cart.

Bought this to fit my Aarke glass bottles. It fits good. Wish it was a bit thicker for the summer but it keeps my bottle safe from bumps.

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

I like it so much that I might even buy a second one. It fits my Nalgene bottle perfectly. It even fits the knock off Walmart bottles I have.

I purchased this for my daughter to use during high school golf. She uses it all the time. She uses it at school, at home, and golf. Doesn’t hold ice like a stainless steel bottle. It does prolong the inevitable tepid water temperature that comes with being a Nalgene and/or Lexan bottle user. The shoulder strap is a nice touch, frees up your hands or should I say index finger specifically.

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
