Rating: 5 out of 5

Great for hot yoga lovers! The fabric is smooth and feels soft during your sweatiest flows. The thick band allows for it to be worn under a crop top as a cute layer. Or, you can just wear it alone as a cute crop top. There is some compression for support, but note: this is not for high intensity workouts. This model improves on the design of the Knix Racerback Evolution bra: instead of a pull-over design, the Knix Catalyst has three back clasps.

The slight compression provides just enough support to keep the girls locked and loaded in downward dog—or in your head-stands.


This is not a do-it-all sports bra, because it is meant to be soft, comfortable, slightly compressive, and supportive. This may not be for people with larger chests.

Bottom Line

Knix made this sports bra for medium intensity workouts. This makes it perfect for any sweaty yoga session. You can wear it all day without the tight compressive feel of most high-intensity options.
