The Freestyle™ Hands-free is Medela's smallest and first wearable hands-free double electric breast pump, designed so you can carry on with other tasks while you're expressing. The compact, pocket-sized pump is a separate unit, allowing our lightweight collection cups to fit discreetly inside your bra for a superior hands-free pumping experience. Note: The Freestyle™ Hands-free only comes with 21mm & 24mm breast shields.
