A protective case protects a communication device and an item, such as credit cards and money. The protective case is fabricated from a material inhibiting moisture, providing buoyancy, and minimizing shock forces. The protective case comprises a first compartment for storage of the communication device and a second compartment for storage of the item. A lid having a seal inhibits passage of moisture in the compartments. A grip portion enhances grip of the protective case. A tethering portion enables tethering of the protective case to a user. A tether locking portion, slides along the tethering portion for length adjustment. An aperture aligns with a socket in the communication device receiving a cable carrying a signal to the communication device. A cap inhibits passage of moisture into the aperture. At least one opening in the protective case enables detachable attachment of the tethering portion and a fastener.
