    So comfy!!

    I absolutely love these! They're super comfortable and I haven't had any issues with leaking at all. I'm surprised by how quickly everything gets absorbed so you don't feel 'wet' down there.

    Fit small. Not enough stretch. Wedgies when walking.

    For a brief these sure don’t give much bum coverage. They are narrow at the bottom and cause wedgies as soon as I walk. And the gusset pad isn’t sewn at the edges and bunches. Not comfortable.
