Willow 360 Leak-Proof Breast Pump Milk Bags FAQs
What sizes are available?
Willow offers Flanges and Milk Containers in size 21mm, 24mm & 27mm. If you are measuring 11mm - 17mm nipple size, we recommend the Willow Inserts with the 24mm Flange or Milk Container for the best pumping experience.
Do I need a special bra for Willow?
We recommend wearing Willow with a full-coverage nursing bra that’s stretchy and has a flap. Avoid underwire and padded bras.
Does Willow work with larger breast sizes?
Yes. Willow was designed to work with larger breast sizes including G and H bra cups.
Can I return Willow if it doesn’t work for me?
Breast pumps and accessories are regulated as single-user product and cannot be returned once the safety seal has been broken. The Willow breakthrough technology is unlike any other pump on the market. If you are having any problems, take advantage of our complimentary 1:1 coaching from our all-mom team of experts.
Do I need to use Milk Bags with Willow 360?
No! Willow 360 offers the option to pump into Spill-Proof Milk Bags or Reusable Containers. Milk Bags enable total 360 degree mobility, while Containers offer 180 degree mobility, superior to other wearable pumps.
Will Willow 360 still work if I produce more than four ounces on each side?
Our Spill-Proof Milk Bags and Reusable Containers hold up to 4 oz of milk (8 oz total). Willow automatically shuts off when your Milk Bag or Container is full. If you pump more than 4 oz in a single session, you can easily switch out the bag or empty the container and continue pumping.
Can I freeze the Milk Bags?
Absolutely! You can freeze in the Milk Bags. Our Milk Bags can be stored in the freezer for up to six months. Our Milk Bags have a convenient tab at the top to record the date the milk was pumped to help keep your stored milk organized.
