The beat swim top ever

Wow - this has to be one of the best swim tops I have ever had! It’s not only incredibly comfortable and extremely practical for ocean swimming, surfing etc, it’s super sexy! The front zipper detail allows you to either have it zipped down for a more casual look or zipped all the way up to catch waves and swim …. I love everything about this brand, but this top is a winner!

So cute sexy and versatile

I’m obsessed with this top! I wear it as a workout top and as a surfing top. It keeps everything in but at the same time has a zipper if you wanna show a little something!
