This nursing sports bra is so comfy, the first night i got it, i slept in it!! Very easily adjustable too!!
Exactly what I never realized I was needing and sooo much more comfortable for daily life including exercising and nursing!
It's surprisingly hard to find a good nursing sports bra, so was very glad to be referred to Born Primitive! The adjustable straps are great, but for me at least, I still found the cup and band size to run a little large, and had to order a size down. Overall very soft, supportive, and well designed.
I love the coverage and how it comes down lower than a traditional sports bra. So comfortable and the straps are super easy to take down and back up for future breast feeding when baby arrives :) . Also the designs are super cute! I’ll continue to wear because I like it so much even after I’m not breast feeding anymore.
Most comfortable maternity bra I have found yet! Runs a little big, I had to size down. But other than that, it’s amazing. Velcro is super easy to use.

Every bra serves a different purpose for different activities and we recommend referencing each specific bra product description to determine the best bra for your body and sport. Our bras should generally fit snug. Wearing the bras too loose will not likely provide adequate support.
***Please note, a majority of our sports bras are medium support and medium coverage. If you are looking for the highest impact support that we offer; check out the X-Factor, Intensity or Moxie Sports Bra!
