    Make more colours!

    This is the only sports bra I’ve ever found that comes remotely close to fitting my large cup and small band/shoulder size well enough to work out in - I wish it came in more colours!

    Fits small

    I ordered my regular size but this seemed to fit really small. Real trouble getting it off!

    the MOST comfortable sports bra I've owned

    I have big boobs and needed a good bra for running (high impact) - this one is it.

    It's comfortable as hell, it's got a mesh vent in the bottom front that helps things air out, the sweat wicking is magical. I worried about how hard it would be to get off when I was sweaty and tired since it's a pull on, but it goes on and off easier than any other pull on sports bra I've owned. As someone else mentioned, the sewn in pads really are easy to adjust. Everything stays where it's supposed to, nothing rubs. I've used it 3 times and am already looking to buy more.

    Soft and smooth sports bra

    This bra fits well. True to size.

    Seems a bit tighter than my first one. But my original may have stretched a bit.

    I like the cups that are partially sewn in.

    Make more colours!

    This is the first racerback sports bra that I can wear that is comfortable and fits like a glove. I even wear it as a swim top because I love the style of it. Please make more colours and/or create a swim top in a style like this.

    Comfortable, good support

    This sports bra is comfortable and provides enough support for my level of activity (lower impact), and the sewn-in pads are pretty easy to re-adjust after washing. Happy with my purchase.

    Sew in the pads

    I have a older version of this and have never had a problem. However, on this one, the built in pads keep moving around and bunching up. If I can’t take the pads out, I need you to sew them down so I’m not fighting to put them back into place. Once they’re in place though, I love this bra - it’s very comfortable.

    Love!

    This is such a great sports bra. Great support for working out and looks great to wear on its own - great for this hot weather! Bought in both colours - please bring more fun prints in this one!

    Wear on repeat!!

    When I tried this sports bra on for the first time, I was a bit worried that I had ordered the wrong size as I could barely get it on but, like the underwear, it took a couple times for it to mold to me and now it is easy to put on, yet still fits like a glove! I love that the pads are not removeable, no moving the pads around to make sure you don't have 'pad lines' across your chest. Lots of support, and quite flattering for a sports bra, you can see that you have a chest! I might have to get a 2nd one as pretty sure I've worn it daily since receiving. Note that it does have a little higher neckline than some sports bras, the neckline is slightly higher than some of my tank tops, but have been pairing it with olive-coloured shorts to look coordinated!
