    I love them!

    I feel more secure wearing these than wearing an actual pad. And they're smooth and silky and feel so nice.

    Love them

    Never tried anything like these before and so far I'm a fan. Only issue I have is that I tend to run between sizes L and XL. So the L I ordered are a bit snug on bloaty days. If your between sizes like me I recommend getting the large in for all around comfort.
