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.

Whether pumping, nursing, or both, manual pumps are a mainstay in your feeding toolbox because they are:

• Compact and mobile, making them travel-friendly and optimal for on-the-go
• Essential for emergencies like power outages and unexpected circumstances
• Offer quick relief from swelling or engorgement

Whether you're managing letdown, relieving engorgement, or pumping in a pinch, Willow Wave gives you full control. Toss it in your bag for travel, keep it bedside for quiet nighttime pumping sessions, or use it as a lightweight backup to your electric pump. It's small but mighty and always ready when you need it.
