*** Please read the sizing information below carefully. It is highly recommended that you double-check your sizing as most people need between 13 and 18mm in regular flanges - click here for a sizing guide and here for an article on why sizing is so important ***

Pair of soft silicone flanges, designed to increase comfort and output*. Designed by 2 exclusive expressing, MIT graduate mums in the USA.

These flanges need connectors to work - these can be your existing connectors or can be added on as an option for $19.95/pair. Note - wide connectors fit Spectra/Pumpables bottles and backflow protectors, narrow neck flanges fit old style Medela tubing^ and standard narrow neck bottles (you can make these work with Spectra breast pumps by adding 'Spectra back flow protector to Medela flange adapter')

Note on sizing - some users have commented that the measurements may not be correct and that they are larger than stated. The measurements are correct, but because the flanges are made from a soft silicone they are flexible and allow for extra movement. It may be best to go down a size (eg if you are currently using 16mm, go down to 15mm). Sizing should be based on the best fitting regular flange you have tried (if you have only used a 21mm or bigger you probably need smaller, see above)
