Find your flange fit. Pump with confidence.
When it comes to wearables, sizing is different — you'll need a fit that's more snug. Most moms find that adding 1-3mm to their nipple size (or 0-2mm if you're pumping with Willow 360) results in optimal output and comfort.

The right size is key for maximizing comfort and output. Willow offers flanges and containers in size 21mm, 24mm, and 27mm. If you measure smaller than 21mm, we offer Sizing Inserts in sizes 15mm, 17mm, 19mm that snap into our 24mm Flanges and Containers. We strongly recommend measuring yourself to determine your Willow size as it might be different from other pumps you’ve used. Unsure of your size?

After every use, you can wash by hand or pop the parts in the dishwasher, top rack only.
- Colleen G.Verified BuyerI do not recommend this productRated 1 out of 5 stars1 week agoTerrible design
I was really looking forward to using the containers. I’m disappointed though and wish I would have went with another pump brand. The containers don’t work and collect as well as the bags, which having to use the bags all the time is wasteful. Not to mention they are a HUGE pain to clean and dry. The design and function of these is terrible.

With perfect use, these function exactly how you want them to. 4 stars only because it’s a learning curve to learn “perfect use”. Customer service VERY helpful. Will recommend to friends and use again in the future!

I love that I can dispense milk into a bottle for use right then. Then freeze the remaining. The 1 & 2 fans are a little confusing. The instructions aren’t very helpful and I couldn’t find a video for this one. It also leaks, which can be annoying. But I do enjoy it and it’s also nice not having to keep reordering bags for the milk

Our 360 Milk Containers offer a wide range of mobility, but are not leak proof in any position (our Milk Bags are completely spill-proof). The dial at the top of the milk container is used to open and close a small air vent hole at the top of the container. When the dial is set in the '1' position, this means the air vent hole under the dial is open and allows for any accumulated air to be released to avoid pressure building up in the container. When the dial is set in the '2' position, this covers the small air vent hole to allow leak free flip to finish. Flip to finish is the last step to ending your session, and transfers any remaining milk from the flange and flextube™ into the container. If you have any questions or concerns, please feel free to DM us on social or reach out to our Customer Care team at 1-888-WILLOW-3. Hope this helps! - DestinyI recommend this productRated 5 out of 5 stars2 weeks ago5 Stars
