    Love this tank top!

    This tank top is so light and love the cut and shape of it.

    It fits beautifully and is super comfortable.

    I love the mesh that helps keep me cool in the heat of summer.

    Would really like this is more colors!

    Nice workout tank

    Good workout tank. Four stars because I didn’t like the shiny material but it washes well and does the job.

    Very cool and definitely moisture wicking. Held up well to an outdoor workout, and it's summer in Florida so that's really saying something. The only downside is that I would say it runs a little small. I ordered a size up from what I would normally wear based on reviews and the size chart and it was a good decision, so I would advise others to consider doing the same.

    Love it! Need more colours!

    This tank is perfect for a workout. It fits nicely, loose enough to not cling around my belly and with armholes that don’t gape. I got it in black, don’t really want white, but want to get more. Red? Blue? Pink? Yes please!

    Active top - comfort meets style

    Love the feel of it. Fits well and doesn’t ride up when working out.

    A bit on the small size - and too short for plus size
