I recommend the razor I always use.

I swim, so I remove my hair every time.
I use this Schick razor whenever that happens.
It comes with soap, so you don't need any other cream or foam.
It glides smoothly and is easy to use, so I've been using it since I was a student.
Only the razor blade is replaceable, so I replace it when the soap runs out.
Try the Schick razor, which is highly recommended for hair removal.
