Willow 360 Pump and Container Bundle: What’s Included and How to Use It

The Willow 360 Pump and Container Bundle is designed for parents who want a complete wearable pumping system right out of the box. Instead of buying parts separately, this bundle pairs the Willow 360 pump with reusable containers, making it easier to collect, store, and feed without extra transfers. Whether you’re new to wearable pumps or upgrading from an older model, knowing exactly what’s inside—and how to use it—helps you get the most value from your purchase.

In this guide, we’ll walk through the bundle contents, show you how to set up and use the pump, and share practical tips for keeping everything running smoothly. We’ll also highlight a few compatible accessories that can simplify your daily routine, from backup parts to storage solutions.

What’s Included in the Willow 360 Pump and Container Bundle

The Willow 360 Pump and Container Bundle contains the Willow 360 pump motor unit, two reusable 7 oz breast milk containers, two container lids, two flanges (with sizing inserts), two Flex Tubes, two duckbill valves, and a USB charging cable. The bundle also includes a quick-start guide and a storage pouch for the containers. Notably, the pump itself is the same Willow 360 model that offers hands-free, app-connected pumping with customizable suction levels.

What sets this bundle apart is the inclusion of the reusable containers instead of single-use bags. Each container is made from BPA-free plastic, holds up to 7 ounces, and seals with a leak-proof lid. You can pump directly into the container, then snap on the lid for fridge or freezer storage. The containers are also compatible with the Smart Storage Bundle for organized milk management.

• Tip: Store the containers with lids on after cleaning to keep them dust-free and ready for the next pump session.

How to Set Up the Willow 360 Pump for First Use

Before your first session, wash all parts that contact milk (containers, flanges, Flex Tubes, duckbill valves) in warm soapy water, rinse, and air dry. The pump motor unit should only be wiped with a damp cloth—never submerged. Once dry, attach the container to the flange by aligning the arrow markers and twisting until it clicks. Insert the Flex Tube into the top of the flange, then connect the duckbill valve to the bottom of the flange assembly.

Next, attach the assembled flange to the pump motor: line up the notch on the flange with the slot on the motor and press firmly until you hear a click. Place the pump inside your bra, making sure the flange is centered over your nipple. Open the Willow app, pair the pump via Bluetooth, and follow the on-screen prompts to select your suction level. The pump will start in stimulation mode and switch to expression mode after a few minutes or when you manually change it.

• Tip: Use the Willow 360 sizing kit (sold separately) to confirm your flange size before first use—a proper fit prevents discomfort and maximizes output.

Using the Willow 360 Containers for Pumping and Storage

The reusable containers are designed to simplify the milk collection process. After pumping, simply unsnap the container from the flange, twist on the included lid, and label it with the date and time. The containers are stackable and fit most standard bottle coolers, including the Breast Milk Cooler Ice Pack for on-the-go storage. Because the containers are BPA-free and dishwasher-safe (top rack), cleaning is straightforward.

One tradeoff: the 7 oz capacity means you may need to empty the container mid-session if you produce more than 7 ounces per side. The pump will pause automatically when the container is full, and you can swap in a second container from the Willow 360 Backup Container Bundle to continue pumping. The containers are also compatible with the Comotomo 8 oz Baby Bottles (2-Pack) for feeding—just use a standard nipple ring adapter.

• Tip: If you pump directly into feeding bottles, consider the Smart Storage Bundle to keep everything organized and labeled.

Maintenance and Replacement Parts for the Willow 360 Bundle

Like any wearable pump, the Willow 360 requires periodic replacement of wear parts to maintain suction and hygiene. The duckbill valves and Flex Tubes should be replaced every 4–6 weeks with regular use. The Willow Go Backup Parts Set includes these items and is compatible with the Willow 360, making it a convenient one-stop replacement kit. The flange inserts may also need replacement if they become stretched or misshapen.

For charging, the bundle includes a USB cable, but you can speed up charging with the Willow Go Dual Port USB Charger, which supports two pumps simultaneously. The pump motor itself is rechargeable and typically lasts 4–5 full sessions per charge. To extend battery life, avoid letting the pump run completely flat before recharging.

• Tip: Set a monthly calendar reminder to inspect and replace duckbill valves and Flex Tubes—this keeps suction consistent and prevents leaks.

Accessories That Complement the Willow 360 Bundle

While the bundle covers the essentials, a few add-ons can make your pumping routine more comfortable and efficient. The Hot & Cold Breast Therapy Packs provide soothing relief for engorgement or mastitis, and they can be worn inside your bra between pumping sessions. The Cooling Gel Nipple Pads offer targeted cooling for sore nipples and are reusable after washing.

For travel, the Pump Anywhere Bag is designed to hold the Willow 360 pump, containers, and accessories in organized compartments. It includes an insulated section for milk storage and a padded pocket for the pump motor. If you pump multiple times a day, having a dedicated bag keeps everything together and reduces the chance of forgetting a part.

• Tip: Pack a spare set of containers and valves in the Pump Anywhere Bag so you’re prepared for unexpected pump sessions away from home.

The Willow 360 Pump and Container Bundle delivers a complete, ready-to-use system for hands-free pumping with minimal fuss. By understanding what’s included, how to set it up, and which accessories support your routine, you can make the most of every session. Whether you’re a first-time wearable pump user or a seasoned pro, this bundle simplifies milk collection and storage—letting you focus on feeding your baby, not your equipment.
