Borosilicate glass gives these five-ounce bottles high thermal resistance for daily warming and sterilization. We pair each bottle with our soft, breast-like S slow flow nipple and a travel storage cap. The four-piece design keeps assembly fast and cleaning straightforward after every feeding session.

We make these bottle bodies from pure borosilicate glass that resists rapid temperature shifts. The clear material stays free from stains and odors through daily cycles in warmers, boiling water, microwaves, and steam sterilizers.
Our size S slow flow silicone nipple flexes naturally to support latching for infants from birth to three months. Integrated vents route air away from the liquid path so milk flows continuously without nipple collapse.
Each bottle consists of only four components: the glass vessel, silicone nipple, collar ring, and protective lid. The wide-neck opening lets you reach inside with standard brushes and assemble the pieces in seconds.
We include two dedicated storage caps in this set to turn the glass bottles into leak-free containers. Snap them on to store expressed milk in the refrigerator or pack prepared bottles for travel.
Absolute favorite bottles ever! Best for keeping breast milk the same temperature throughout without having random cold and hot spots. Super thick glass material. Light weight and perfect for any size hands. Had little to no leakage unless the bottle was left upside down due to my forgetfulness. They work great as smoothie and yogurt containers now!
We love these. I think the 5oz are so useful. The only downside I could see is maybe if your child doesn’t like the nipple but we haven’t had that issue with two of our kids. Also haven’t needed extensive anticollic systems. This just makes sense.
