BEST EVER!

I now have 3 .... this is the BEST sports bra. I love it! I use to only buy racer back sport bras, but I took the chance on the Catalyst and the straps don’t move. This bra also feels like It’s not even there. No matter what you like : yoga or Steel mace to running marathons this bra will make your GOALS happen!

Best bra EVER!!!

I have been searching and struggling for many years for a bra that is both comfortable and super supportive, but also fits my body type (32E). I have struggled for so long, but that is FINALLY over with the Knix Catalyst sports bra. I use it as my everyday bra and love the wireless feature and the great quality of material. The ONLY thing I wish to make it even better, would be for Knix to have it available in a white or nude color. Hint hint Knix. ;)
