The Osmo Action Floating Handle helps the camera float in water. The waterproof case protects your Osmo Action in water at depths of up to 60 m. The wrist strap enables you to fasten the camera to your wrist so that you don't have to worry about dropping it when you swim, surf, or enjoy other water sports. An extra battery provides a longer shooting time. All these accessories can be easily packed in the convenient Osmo Carrying Case so that you can take them wherever you go.
