    Catalyst Sports Bra

    Love this bra! Very supportive but comfortable. My only concern is that when the bra is brand new, it is very hard to stretch it so very difficult to fasten. I almost thought I had ordered the wrong size. But, once I got it fastened, it was ok.

    Love this bra!

    I wear this as a regular, everyday t shirt bra. It has great support and looks smooth under t shirts.

    Jumping Jacks Approved

    Instead of my usual Catalyst Sports Bra I actually wore a different bra to the gym this morning and had to hold my boobs while doing jumping jacks! What was I thinking?? Never again will I deviate from my Catalyst for high impact sports. True story.
