    Steps aren’t long enough for tall women

    Great concept but straps aren’t long enough. I actually required assistance to remove it.

    Go-to sports bra

    My favorite sports bra style for medium to high impact activities because of the comfort and great job it does limiting bounce.

    KNIX, WE HAVE BEEF!

    This bra is THE MOST size inclusive, heavy duty, high impact, easy on/off sports bra I've found in Canada. I was so happy to have found it to replace my favorite Adidas one that was discontinued. My size 8++ was sold out in cute colors for a while so I was waiting to pull the plug to build a collection. WHY DID YOU DISCONTINUE IT KNIX?!?! WHY WHYYYYYYY.

    I feel like the front zip makes the most sense to avoid the stretching out of the band when like me you have to clasp in the front then twist around. Shefit is the closest alternative I could find but it's in USD and shipping/duties makes it not worth it. Why knix, whyyyyy, you break my heart and all I've done is be a stan and support and buy sooo many of your products 😭😭😭

    Catalyst is the best for larger bust support

    Catalyst is the only bra style I have worn for years. It is amazing for larger busted (34E) women who want as much support as possible, without feeling like body armor. It is almost seamless, nice wide straps, extremely good quality that lasts years. This is the first time I have tried the front zip Catalyst, and I don't love it compared to the regular version. The front zipper has a bulky top on it that can be seen through clothes, and the racer back is gives me neck pain, but for a racer back sports bra it is as good as it gets.

    Comfortable ut a bit snug at first

    I had to exchange si e and the process was smooth. The bra fits well other than being quite snug at first. I would recommend very comfy.

    Zipper end sticks out

    I really like this bra. Support, strap width, versatility of the straps….. only negative is the zipper end bulges out and no matter how much I try to tuck it in, you can definitely see it when wearing it t-shirt

    Not great for a full bust

    First of all, Knix bra sizing is way off. Whatever your regular bra size is, go up at least two more sizes. When I did get a replacement in what's my correct size for Knix, the design and build of the bra isn't great. It pushes everything up way too much and creates a bulge at your arm pits (even though the size is correct, it's just the design of the bra). Also, the zipper creates a bulge that if you have a shirt over it, it looks like you have a third nipple.
