The Medela Hands-Free Collection Cups are designed for use with your existing Freestyle Flex or Swing Maxi double breast pump. These ultra-portable collection cups transform your current breast pump into a hands-free pumping solution for ultimate flexibility. The collection cups fit into your bra to facilitate pumping, and the lightweight design allows for multitasking while pumping. The anatomically shaped collection cups consist of only three parts that need to be cleaned and come in two sizes to ensure comfort and flexibility.
