  • The easy to use nursing clips that you can manage with one hand.
  • The moisture-wicking, quick-dry antibacterial fabric. It quickly absorbs and disperses any moisture making your crop a lot more comfortable.
  • The wire-free design. Not only does this make the crop super comfortable, but going wire-free has been shown to help reduce mastitis.
  • The removable padding and easy access pocket for breast pad insertion.
  • The comfortable, four-way stretch material. It holds its shape and moves with you. It will last for a long time.
  • The thick elastic band that offers extra support and lift under the bust.

    Super supportive

    Great supportive bra. Easy to access for feeding too. I’m a 12DD/12E and wear a medium. Could do with adjustable straps at the back.

    Needs adjustable straps

    I have large breasts and unfortunately this bra just doesn’t give me enough support to wear it to the gym (CrossFit). I feel that it needs adjustable straps, as my straps already seem to be too stretched/loose to support well. It is quite comfy to wear around the house.

    Good but could be more supportive

    I’m usually a medium, but due to my bust growing during pregnancy I ordered a large. It fits, but I am not one that likes when the straps go inward, not covering the outer part of the chest for fuller coverage. Otherwise good product.

    Awesome product

    I am currently breastfeeding my 6th baby, so as you can imagine have spent a small fortune on sports nursing bras. I ordered 2 from Mummactiv and I have to say, these are the BEST ones I have ever used... The support is amazing, no more holding boobies down at our camp... 🙏🏻💖
