CaraCups make hands-free pumping easy! Unlike traditional bottles and flanges, Spectra’s CaraCups are placed in the bra, allowing moms to express breastmilk hands-free. CaraCups are lightweight, BPA/DEHP-free, operate on a true-closed system and are compatible with all Spectra® breast pumps, among other brands. Transferring breastmilk into preferred storage after pumping is easy and sanitary.
