Not the Same Catalyst Sports Bra I Have Purchased in the Past
I have been a Knix customer for a few years and was a big fan of their Catalyst Sports Bra. I'm sorry to say that when they changed their sizing guide, it was more difficult and not as accurate as their previous sizing guide. I had lost weight recently and sought guidance on how to get the right size. I used their sizing chart and didn't believe the size it told me to purchase, but purchased anyway based on what the sizing chart said. Big mistake. The fit was ridiculously small in cup size. I had a chat with a Knix representative, but even then was told to buy the same size. I disagreed vehemently with the recommendation and decided to go up a cup size. I'm still not confident that I am in the correct size, because, to put it bluntly, I'm falling out all of the place. For the price of the Catalyst Sports Bra, I don't think I will buy any more from Knix, because I just can't find the right fit. I also think they have changed the bra somewhat. Regardless of the cup size issue, the band doesn't seem to fit against my body in the front. The gap allows my breasts to fall out from underneath, so I am constantly having to adjust myself. I also feel the material isn't the same. Overall, this has just not been a good experience this time around.

No bounce!
I am large breasted and have difficulties finding a sports bra that accommodates my asset without straps digging into my shoulders while reducing front end mobility. I love how the catalyst packs in my boobs and keeps them in place. At first I had doubts about the short and wide straps not having any give but that’s what prevents the bounce when I’m running. The generous cut also keeps sideways spillage under control. This bra is so comfortable that I can wear it all day long.

A good shape but not good quality
I like shape this "sports" bra gives however the quality is pretty poor after only the first wash/wear the hooks already were coming off. Also the fit pinches a little bit underneath in the front. It's expensive for this kind of quality especially. With something made out of "plastic" essentially you would hope it would last more than a wash/wear/
