The pump adapters actually fit my Spectra flanges, so I can pump straight into the bag and skip washing an extra bottle. The double zipper seal gives me peace of mind when I lay them flat in the freezer.

I freeze about 40 bags a week and these haven't leaked once, even stacked flat in the freezer door. The 6oz size is perfect for my morning pump sessions and the double zip seal gives me peace of mind.

The pump adapters actually screw right onto my Medela so I can pump straight into the bag and skip washing an extra bottle. The double zipper seal hasn't leaked once in the freezer, even stacked under heavier stuff.
