Koverz for Kids - #1 Neoprene Baby Bottle/Sippy Cup Insulator Cooler Coolie - Boys Blue 4-Pack

I love these. My little guy is picky about the temperature of his bottle and during the winter time it would get too cold before he could finish it. I'd put one of these on right after I made the bottle and it kept it warm. I can also put steaming hot water in a bottle, cover it with this and throw it in the diaper bag. By the time I need it, it's a really nice warm temperature and stays that way for at least an hour or two. I just wish they came in different sizes. It's too big for a 5 oz bottle and too small for a 9 oz bottle. But I'd still buy again and recommend because they work really well and are super cute.

I am super glad I bought these consideing how hot it's been where I live. The designs are adorable and they really so keep my child's sippy cups cool for a longer period of time. It does take practice to learn the best way to slip them on, but once they're on you won't have to worry about it falling or sliding off cause it's almost like a second skin to the cup. My child loves to take things apart and he/she has yet to even slide it off a centimeter. What's nice to is that it absorbs the condensation (especially if we're outside in the heat for an extended period of time) so the outside of the cup isn't slippery or dripping everywhere. It's machine washable too which is a plus.

It been 100°+ where we live. So I wanted to get a koozie for my 1 year's sippy cup. It works GREAT! It'll keep it cool for hours while we run errands. When it's directly out in the sun, it'll stay cool for 45 minutes + but by then, he's already drank the water lol and it keeps his hands from getting wet when the cup his sweating. I would definitely order this again and recommend it to others! Didn't forget to mention that we used Nuby 12 oz cups???? And it still fits! Yes! I just wish that when you buy them bundled like this that you could choose a theme instead of random ones.

The little one uses Avent Natural bottles, and has gotten to the stage where he only drinks part of his bottle. I was looking for something to keep is cool, to avoid tossing the rest of the bottle, and wasting the expensive formula that he consumes. This is perfect. The formula is still cool, not refrigerator cold, but not room temp either. Not only does it work with the bottles, it also worked with the Take n Toss sippy cups. When it gets too grubby, toss it in the wash, and let it air dry. Perfect!

Great quality and insulates bottles and sippy cups well. I decided to get rid of all the plastic sippys and use glass or stainless steel. I've found that with the stainless steel, the bottle can get really cold and hard to even hold, especially if there is ice in it. The Kidzikoo is the perfect solution. We have the Kids Kanteen and the Pura sippy cups. The girth of these two cups are pretty drastic compared to one another, but the Kidzikoo fits both - bit tight for the Kid Kanteen and a bit loose on the Pura - however they fit.

I bought these to go around half pint jars, and they are a very tight fit, but a little too tall for the half pints. It can be a little tough to get them on for that reason. The prints are nice (although I take issue with the labeling as "girls" and "boys"--if you want to specify with pink colors, just say with pink colors), but I wish I could mix and match more easily. I've washed them with no issues, and they seem to be well made. We've been using them for at least a month, and they are holding up thus far.

These work great. They are easy to use - just slip on. it's great for the bottles because they are metal. When you put cold drinks in them the metal gets cold and our son doesn't like holding the sippy cup. When they get dirty we just quickly hand wash them. Would buy again.

If you have Replay cups and your kid has Sensory issues, then get these! He loves the replay, and won’t drink water unless it is cold. So we got these because with having cold water he was not able to hold the cup with out his hands getting ice cold. So we found these and they are awesome!
