    Best bra ever!!

    I absolutely love my new white Catalyst Sports Bra!! I love it so much that I bought another in black and will be purchasing another. It’s super soft and extremely comfortable. I wear it as my everyday bra. I tried other popular name brand bras and sports bras. None can hold a candle to KNIX. You should definitely give KNIX a try.

    Best bras ever

    I have fully replaced all my sports bras with the catalyst. The first could wears are a bit annoying with how tight it fits but it loosened up and was very comfortable after about 3 washes. They hold up so well, especially to regular washing. Really holds everything in place and no uniboob.
