This set leaves nothing to be desired. With the ingenious Calypso-to-go electric double breast pump and practical breastfeeding accessories, you are perfectly equipped and can stay mobile at all times thanks to the attractive nursing bag. The accessories also include a cooler bag with cooling packs for storing breast milk. Vacuum (suction strength) and cycle (pumping speed) can be individually adjusted at any time. The electric double breast pump can be operated with batteries or a power adapter. Three different breast shields are included for various nipple sizes. Maximum safety, hygiene, and protection against pathogens or contaminants are ensured by the VacuuSeal technology. The OptiFlow massage insert actively massages the breast, providing efficient and comfortable pumping in conjunction with the particularly gentle suction behavior of the Calypso. Both double and single pumping are possible. The appealing and compact design, along with the quiet operation, allows for discreet pumping.
