Can I use the cup on the beach or in the swimming pool?

Yes. You can use the cup with no limitations in any water-related activity, be it bathing or swimming. Moreover, you need to change the tampon after every swim while the cup has your back all the time. Simply empty the cup before you hit the beach or the pool and you do not have to worry about a thing until you come back home. The cup really does not care whether you are just comfy at home or at the beach.
