Here’s how the Willow Go pump stands apart from the Elvie Double pump. 

The Willow Go and Elvie Double pumps are consistently rated highly by moms looking for a sleek, discreet, hands-free pump. They are both fully in-bra and built without clunky motors, tubes, bottles, or cords. They are app-connected and controlled; dishwasher safe (minus the pump itself); and offer comprehensive flange sizing support.

Yet despite these similarities, there are a few key differences that you’ll want to keep in mind when choosing the wearable pump that’s right for you. 

Below, we’ll share more about what makes the Willow Go unique, and share some thoughts from real pumping moms. 

Hospital-Grade Suction 

The Willow Go is built with 15 levels of hospital-grade suction (up to -280mmHG per side) and the ability to customize your suction on each side for optimal output.  

While Elvie Double also features multiple levels of stimulation and expression that can be customized per breast, the suction is not hospital-grade. (You’ll only find hospital-grade suction in their Elvie Stride pump, which is not fully in-bra — tubes, and a small motor must be clipped to a waistband.) 

Cost & What Kind of Insurance Coverage You Can Expect 

Both the Willow Go and Elvie Double are partially covered by insurance — you’ll find this is true for many wearable pumps. 

However, the Willow Go is a more affordable pump, regardless of whether you buy a set or just a single pump. 

• Willow Go - $349.99 (double), $179.99 (single)
• Elvie Double - $549.99 (double), $299.99 (single)

Pump Design

While both Willow Go and Elvie Double are fully in-bra and designed with a shape that mimics the breast, only Willow Go has an internal, donut-shaped motor that allows for the even distribution of weight — and more comfort when pumping. In fact, 8 out of 108/10 moms say that Willow Go is more comfortable than their other wearable pumps.

The Elvie Double motor sits on top of its container, leading to a more “top-heavy” pumping experience.

Container Design & Options for Milk Collection

Willow Go is compatible with 5 oz or 7 oz containers, giving moms options for capacity. (The 5 oz containers give the pump a lower profile, while the 7 oz containers are great for high-output sessions.)  

The Elvie Double, on the other hand, is only compatible with 5 oz containers. 

Moms also love that Willow Go containers are fully visible when pumping, making it easy to see how much milk they have pumped. Elvie’s containers, on the other hand, are covered by a motor that sits on top — so it’s not possible to look down and see how full they are.

Sizing Support

When it comes to flange sizing, both Willow and Elvie prioritize helping moms find the right fit. 

Willow Go comes with: 

• 24 mm flanges
• 21 mm flanges
• Option to purchase sizing inserts (ranging from 13 mm to 21 mm)

Elvie pumps come with: 

• 24 mm breast shields 
• Nipple cushions
• Free sizing inserts based on your size 

Willow Go, however, stands out with a US-based customer care team that’s made up of mostly moms. These Mom Coaches lead weekly virtual group sessions — free for any Willow Go pumper — to help moms measure their nipples, find the right sizing insert, and more. 

What else to know about Willow Go?

All Willow pumps have been designed and clinically tested for more comfort and milk output, featuring a wider flange cone and longer flange tunnel for effective milk expression and less chance of nipple abrasion. The numbers* speak for themselves: 

• 7/10 moms say they use Willow Go as their primary pump.
• Most moms say Willow Go gets better milk output than their other wearable pumps. 
• 85% of moms moms say Willow Go is easier to use than their other wearable pumps.
• 82% or 8/10 or most moms say Willow Go is more comfortable than their other wearable pumps.

Here’s what moms have to say about Willow vs Elvie.

“LOVE LOVE LOVE the Willow pump! I used to have the Elvie original and this is so much better! No leaking. I use the 19 mm Willow inserts and I have the same output as my Spectra. I haven’t even touched my Spectra in a week! Love this! Thank you, Willow! 

“I’ve had the Willow Go for a couple weeks. I was using the Elvie prior. The suction on the Willow is much more comfortable than the Elvie. It feels closer to my baby latching. I even get more output from the Willow!”

“This is literally the best pump out there in my opinion. I tried the Elvie OG and my supply completely tanked and I had to go back to my Spectra. Since I’m in nursing school and work full time a wearable pump was just a need and I’m so glad I decided to go with the Willow Go, 10/10..”
