A double wearable manual pump that lets you express both sides under your clothes and doubles as a hands free kit for many electric pumps. Manual pumping still takes hand effort on both sides.

Overview
Pumping both breasts at once while fully clothed is what the Willow Wave makes possible. Two ergonomic handles drive near silent, two phase suction into wearable containers, and the cups also convert many tethered electric pumps to hands free.
Willow covers two needs in one kit, a quiet manual backup and a hands free upgrade for a corded electric pump. Only one flange size comes in the box, so other sizes mean an extra purchase.
Who it's for
Commutes, meetings and power outages are where a wearable manual pump earns its spot, along with hands free sessions on a compatible electric pump. Parents who need a different flange size should order inserts too.
Pros and cons
- Pumps both sides at once
- Wearable under clothing
- Near silent operation
- No charging required
- Only one flange size included
- Manual handles need effort
- Compatibility list not fully named
Performance notes
Suction comes from squeezing each handle, so output and comfort depend on rhythm and correct flange fit. Two phase suction mimics a let down then expression pattern.
