I purchased this cover to encourage my little lamb to hold cold bottles. My lo doesn’t drink warm milk so I can not speak to hear retention. The material stretches so it was able to fit the wide glass bottle. The advertisement doesn’t include the wide 5oz Dr Brown bottle but this definitely fits it.

Keep bottles safe.

This fit my 4oz glass nuk bottles perfect and is so helpful for keeping the bottle warm when we are heading out of the house! I also just love the cute prints on these!

Fits perfect on 4 oz glass Avent bottle.

This is just what I was looking for! It fits our 8OZ Dr Browns bottle perfectly and keeps the milk cold for short trips. It is made out of great quality and the pattern is so pretty in person. I would recommend to all my mom friends.

Fit perfect on our advent 4 oz glass bottle. Seems like a durable material. & The little handle is perfect for holding.

Fits Philips Avent Natural Glass Bottles perfectly.

Used with dr browns 5oz wide bottle, worked as intended. Good quality..

This is perfect for my glass baby bottles. It fits perfect and is just my style.

I thought I was just going to get a product to keep the milk to temperature. I certainly got that and more. It enabled me to feed her one handed. She would rest on my forehand and I can bend my wrist to tilt the bottle towards her. With the grip handle, it made it so much easier and I would get less cramping. Now I have a free hand to change the channel or use my cell phone. The world is now your oyster.
