The zipper is just... not easy to line up. It's not that it doesn't fit, because it actually lays as if it were made for me. I ordered this more because I wanted a solid neutral sports bra with a pocket. I did try zipping it before putting it on. It made it a little easier, but not enough. Also, isn't the whole point of the zipper to make it easier to put on?
I usually wear a large and my cup size fluctuates throughout the day due to nursing. I went with the medium and it fits perfectly for higher impact activities like running.
I got one of Senitas nursing bras but it was kinda clumsy to unlatch so I kinda gave up on wearing a nursing bra. Then I found the Max Out bra and it's AMAZING. The zipper is convenient (I thought it would annoy me but it doesn't) and I can use as nursing bra if necessary. I have both the black and herringbone and would love it in more colors.
I do not understand why all sports bras aren't made with the zipper in the front. So easy to get on and off Especially after a hot/sweaty workout. There's not struggling to pull anything off over your head, no getting tangled, no messing up the perfected messy bun. Simply ZIP!
