Customers praised this sports bra for its "soft and durable" fabric and comfort. Many found it "very supportive" for workouts with "great bust control." The ribbed texture and included padding received positive feedback. However, some noted it functions more as a "crop top" for larger busts, lacking adequate support for intense gym activities. The square neck design wasn't everyone's preference.

  • The quality is extremely good. It fits perfectly and is very comfortable.
  • One of my favourite bras, fits perfectly, it's comfortable and has a lot of bust control.
  • The fit and colour is absolutely perfect, ticks all the boxes.

Great for casual, not for gym!

“Crop top” rather than “bra”. For larger sizes would need a band underneath bust line to offer support. Otherwise great fabric and fit

We would love to help you find your perfect style and fit, please feel free to reach out to our customer experience team at orders@musclenation.org xx Team MN
