Willow Go offers the best of both worlds — built with hospital-grade suction and a comfortable tug-and-release latch (the same you’re used to if you’ve used other wearables or a traditional pump) while fitting fully in-bra. It’s proof that you don’t need to sacrifice comfort and convenience for output.

Traditional manual pumps haven’t been updated for decades. Until now. Willow Wave is the first and only wearable, fully in-bra, manual pump designed to give moms the discretion, comfort, and convenience they deserve. It’s engineered with an ergonomic handle to reduce wrist discomfort and hand cramping, and is made with a soft, silicone, 24 mm flange for a smooth fit and optimal milk output.

We know every ounce matters when it comes to pumping and breastfeeding, so we engineer our pumps to optimize milk expression.

Willow Go offers maximum suction of up to -280 mmHG per side. It’s also a closed-system pump, just like hospital-grade pumps, to keep your breast milk separate from the pump mechanisms for cleanliness and hygiene.

Willow Go holds up to 5 oz of milk (10 oz total). If you pump more than 5 oz per side, purchase our 7 oz containers to pump up to 14 oz per session (sold separately).

Willow Go is an electric wearable pump known for its one-of-a-kind design that’s engineered for more comfort and optimal milk output. It has a longer, smoother flange tunnel than other brand wearables; a unique internal circular motor; hospital-grade suction; and a tug-and-release pattern that mimics your baby’s natural rhythm.

Willow 360 is an electric wearable pump renowned for its 100% leakproof mobility, so you can pump in any position, even while laying down or bending all the way over. It has Apple Watch connectivity and a continuous latch, making it optimal for moms who work in the medical and first-responder fields.

Willow Wave is a manual pump known for its comfort, discretion, and mobility. Its unique ergonomic handle, a dual-expression switch, and fully in-bra cup make it the first of its kind.

All Willow users have access to the Willow app, which connects moms to our science-backed articles, postpartum resources, and feeding experts.

A passive pump creates gentle suction to help relieve swelling, pain, and engorgement or to gently induce letdown. At 3 oz., it is not meant to promote output, but instead as a breast care tool while nursing or between feeding sessions.

Catch cups are ideal for catching leaks on one side while nursing or on both sides between feeding sessions. It can also protect sore nipples from chafing by creating space between breast and bra. It does not have suction, so it will not induce any sort of letdown.

Willow Wave is a manual pump known for its comfort, discretion, and mobility. Its unique ergonomic handle, a dual-expression switch, and fully in-bra cup make it the first of its kind. It uses suction patterns and strength just like an electric pump so it helps to promote output and remove milk in a similar manner.
