Eximius Power Beer Bottle Party Drink Coolies Pack of 4 Color Sleeves - Bonus Fidget Opener

They're a bit small, and they don't stretch as much as you'd like, but they work just fine. Probably advisable to put them in something that'll hold them upright, as the bottoms aren't completely flat when you put something in them. A cup-holder or a can-style drink holder both do fine.

Nice snug fit. Keeps the beverage cold. Would be 5 stars if they price were less and there wasn't advertising on them.Update 2019-Jan: Six months in and they've held up well through football season.

Seem to do a good job.

Keeps bottle cool quite a while. Only issue is be sure to put it on the bottle BEFORE you remove the cap. Very tight fit on any bottle I have tried.

Vibrant colors and thick stitching. Zipper seems good quality too, but they only zip up all the way on certain beers.

I can't even zip up the zipper with a 12 Oz. beer bottle. "SweetWater beer bottle"

These are great! Bright and has a color for every member of the family (except kids, of course!) Fits like a glove, and no leak through at all. Kept my beer nice and cold! Easy to use.

Fits the standard bottle sizes I use. Very thick insulation. Keeps my beer cold longer than it takes me to drink it. Great product.
