Wide neck for easy cleaning and filling. Unique base and sealing cap make it safe to mix feeds in the liner.

As your baby feeds, the liner collapses - so no air is swallowed. Result - less air, less discomfort. (use a pre-sterilized liner for each feed).

Use with the Avent Isis Breast Pump to express your milk effortlessly directly into the liner. (all Avent bottles and nursers can be used with the Isis Breast Pump).

Secure liner with clip (sold separately) and leave liner in holder base to facilitate handling, storing and re-heating.
