4oz (Set of 3 pcs) Miracle Bean Neoprene Baby Bottle Sleeves – Adjustable Sleeves. Glass Bottles – Improved Heat/Cold Retention – Moisture, Non-Slip Grip – Fox, Elephant and Heather Grey

I am really happy this option for Avent Natural glass bottle sleeve protectors have become available. I bought the 4oz glass bottles somewhere about two months ago, and only then the option was the silicone sleeves by Ola baby. Don't get me wrong, I consider that a 5-star product myself, but being a family on a low income budget the sleeves PLUS shipping price adds very quickly to the cost. These sleeves cost me pretty much $12 for TWO sleeves! (Plus the addition of it being free two-day shipping for prime members!--not the case for the Silicone sleeves). So cost wise, they are excellent! As for quality, these sleeves ROCK! The neoprene material is VERY thick -- VERY nice padding for the bumps and falls (I have dropped my bottle on a hard surface twice with these sleeves on and no breaks!) and the material can supposedly insulate hot and cold -- I personally haven't tested that out since i usually keep my baby's formula room temp. Hopefully another reviewer may be able to review on that aspect of it. But back to it's the ability to protect, I'd personally say this product protects just as well as the silicone sleeves OR BETTER*. And if you want my honest opinion, i think it protects the bottle more than it's competitor by a small fraction. Just an opinion... Hasn't been "professionally" tested, lol. I like that the bottle can be taken in and out of the sleeve VERY easily by undoing the velcro. No need for water to help slide anything in or out, like the silicone one requires. It fits tightly around the curves of the bottle. As with the velcro, I will watch to see how it holds up. It seems strong, but time will tell and I will update if it tears apart. I don't really anticipate that happening though unless you are man handling it, haha :D It's water repellant (forms water droplets instead of absorbing the water) though not necessarily waterproof (it does eventually absorb and gets wet when enough water gets on it). The prints are really cute and I honestly believe this was a genuinely great buy! I'm SUPER glad i stumbled upon these sleeves! It definately a 5 star product. I HIGHLY recommend this product! Now, once they start selling some for the 8oz bottles, I will be happy! Gonna email the seller to find out! Gotta buy those too!*Pics included!*

I received these really quickly and they fit the Avent Natural Glass bottles perfectly! I have not used these yet as my little pumpkin is not here but I love the ease of getting them on and off the bottles, I also love how thick they are! I think it will work great at keeping the glass bottles from breaking and helping to retain heat so the bottle stays warmer longer. I also purchased the plastic type of sleeve as well and they were much more difficult to get on to the bottle they also did not fit as well. With these neoprene sleeves you would only need a few as you can easily take them off and on the bottles as you need them, with the other sleeve that I purchased I would need one for every bottle since they are much more difficult to use, I find that impractical due one to the finicial aspect of paying 7.00 more for each bottle and the other reason is adding another step to the washing and putting away of the bottles when I take them off and put them back on. As you will also see in the pictures I posted there is a gap at the end of the plastic bottle sleeve between the sleeve and the bottle I have not figured out a way to prevent that.

These are a bit cheaper material/quality compared to the actual Avent brand sleeves, but they get the job done just the same. I haven’t dropped one of the glass bottles to test it out, but I’m sure it would hold up just fine. The Velcro placement doesn’t match up perfectly, but it is snug enough on the bottle to not fall off or slide around too much when you’re holding it, so for the price I’d say these are a good buy.Note: if you found this review to be helpful, please click the HELPFUL button below!

We used these on our daughter's glass bottles and they really protected them! I was happy with the material in that they were easy to clean and they were malleable enough to fit to the bottle. However, around the velcro latch, it wasn't quite loose enough so ours started to pull and eventually started making a hole where the base velcro was. No big deal in the long run because the good definitely outweighed this minor hiccup but just a note for the future. I would also LOVE to see more print options :)

I feel a little bad about taking off a star because bottles that fit nicely will do well I’m sure. I used this to insulate cold formula bottles at night so they could be prepared before the next feed and sit out longer. However, all of our plastic infant bottles did not fit (would roll around or fall over) because the bottom of this is quite narrow. Make sure you size it right! Does not fit tommeetippee bottles

These do the job as described but I've discovered I really don't need them. I use only glass avent bottles and bought these because I was concerned about accidental drops. Even with multiple caretakers we haven't broken any so we've all stopped using these. I can't attest to the insulation properties because we usually prepare the bottle right before feeding.

The price for these was the biggest selling point. We use glass Phillips Avent bottles for our little one and daycare requires some sort of sleeve. This was the best option for the price. The quality is ok... the Velcro is peeling and sticky underneath after a couple of months of use (2 days/week daycare), and I’m afraid to wash these in the washer in case the Velcro falls apart. They’re otherwise difficult to clean. The material itself feels really strong and cushy, it’s just the Velcro finishes. Great for the price, but not sure how long they’re going to last because of that.

These make it possible to hold a hot glass bottle right out of the bottle warmer, a big plus when you have a fussy baby. I'm not sure they'd prevent breakage, and I've thankfully not had to test that yet. They seem well made. I would prefer if they came in solid colors as I'm not in love with the two patterns offered, but that certainly doesn't interfere with the function of the sleeves.
