Our original (Gen 1) Breastmilk Bottle was a groundbreaking evolution of the baby bottle. The domed base spread milk out to enable faster cooling and warming (learn more about how it works).
Our fully redesigned and updated Gen 2 Breastmilk Bottle offers the same convenient benefits as the original, but with fewer parts to clean and assemble! The new bottle also has a smaller footprint, making it more convenient to store and transport, but it still holds the same 5 oz. volume.
You can easily tell the two apart because the original Gen 1 bottle has a white base that separates from the rest of the bottle. The new, Gen 2 bottle has a clear, one-piece body.
