A wrist strap assembly for a mobile device includes a case and a wrist strap. The case includes a bottom wall. A sidewall is disposed around a perimeter of the bottom wall and extends from the bottom wall to an upper distal end of the sidewall. The sidewall and bottom wall define an inner cavity sized to receive a mobile device therein. A channel is disposed around the upper distal end of the sidewall. The wrist strap is configured to have a stored position and a deployed position. When the wrist strap is in the stored position, the wrist strap is configured to frictionally fit within the channel of the case. When the wrist strap is in the deployed position, the wrist strap is configured to fit around the wrist of a user and to be connected to the case to secure the case to the user's wrist.
