Bathmate Shower Strap for hands free pleasure. The Shower Strap was engineered to allow you keep your hands free when using the Hydromax or Bathmate Hydropump in the shower. The adjustable nylon strap hangs comfortably around your neck and has a hard plastic ring fitted to the end that attaches to pump to take the weight off. This ingenious device allows you to continue to shower normally without having to worry about holding you Hydropump during each session.
