Now you can express while working, while playing with your little one, or even while you drive. The Spectra Handsfree is a set of collection cups that attach to your breast pump and fit securely and discreetly into your bra. This enables you to express milk while – as the name says – having your hands completely free! Available in 24mm and 28mm, the Handsfree is compatible with the Spectra S1, S2, M1, and Q Breast Pumps.
