This lightweight wearable for wilderness activities, which includes a backpack and navigation system, consists of a non-powered hydraulic exoskeleton and AR smart glasses. It uses a bionic skeletal structure to fit the human body for a comfortable use experience, a hydraulic system to always provide assistance to the body support side during walking, and a mechanical leg structure to disperse its own weight and back load, solving the problem of carrying supplies and physical strength. The AR glasses use satellite systems to provide all the necessary data for the personal safety of the user.
