The short version

  • Pumping parents who carry bags to work and like the transport pouches
  • Anyone who wants measurement marks and a big label area
Skip it if
  • You often pump more than 6 ounces in one session
  • You want recyclable storage bags
  • You prefer a pour spout for transferring thawed milk

What owners like

  • Durable double layer material and a double zipper seal meant to resist leaks
  • Freezes flat for stacking in a crowded freezer
  • Included transport pouches are handy for taking bags to work or travel

Common complaints

  • 6 ounce capacity is small next to 7 and 8 ounce bags from other brands
  • Plastic is not recyclable

Based on The Amazon listing for specs, the Aeroflow Breastpumps product page that repeats Medela's own description, Medela's article on using its storage bags, and the Mom Loves Best guide to breast milk storage bags. Independent owner discussion specific to this bag was thin, so these themes lean on the editorial guide..

What it does

A box of 100 pre-sealed, self standing 6 ounce bags for storing expressed breast milk, with measurement marks and a write-on label area.

  • Stands up on its own while you pour milk in
  • Lays flat for space saving storage and quicker thawing of frozen milk
  • Measurement marks for checking volume
  • Large write-on area for the date and other details
  • Comes pre-sealed so the inside stays clean until first use
  • Transport pouch keeps unused bags clean and together

A solid choice for parents who want sturdy, double zipper bags that stand up while filling and lie flat in the freezer. The trade-offs are the 6 ounce capacity, which is smaller than some rivals, and plastic that one editorial guide notes is not recyclable.

Nuliie Breast Milk Storage Bags with Pour SpoutBetter if you pump larger sessions, since the bags hold 8 ounces and have a side spout$$
