3-in-1 ONLY Adjustable Can/Bottle Cooler | ONLY Lightweight Indestructible Beverage Cooler | Fits Most Bottle Shapes and Sizes | for Hard Seltzer, Beer, Soda (White, Single)

My niece loved it and it fits any size can or bottle. She said it kept her drinks cold.

Absolutely perfect, Koozie that finally holds my MONSTER bottles :) Absolutely love it

Pain to open holds large bottles

Keeps beverages cool in the sun. Fits about every container except large Gatorade. Multiple colors available for those who won’t share.

I like its versatility, and I like that it’s so lightweight and flexible. The hard sided ones can be unwieldy sometimes. So, the hack..it doesn’t keep drinks ice cold for very long, but if you store it in the freezer and freeze just the thinnest layer of ice in the bottom, it keeps the drink quite cold longer. Also, as another poster noted, it doesn’t hold the slim cans perfectly, but it you use a straw it works well.

While it doesn't fit EVERYTHING, I still really like it. With all the computer stuff and art supplies on my desk, condensation is always an annoying issue. Normal coasters don't hold everything and can still get stuff wet. The Monster Cooler keeps my desk dry and my drinks cold. Also the wider base keeps my drinks from falling over on my messy desk.

We wanted a cover to fit soft drink and water bottles. Because it comes in 2 pieces, it does fit the height, but but it is too big around, and doesn’t keep the beverage cold for as long as I had hoped.
