VR One, exhibiting the contours of the human body, represents the core concept of the design. For convenience of changing, the battery parts, located on the lower right and left of the backpack, can be assembled from all directions. This also augments balance and reduces the weight burden. To further enhance user’s comfort, the VR One backpack has a special ergonomic frame support, ensuring close contact with the back and at the same time adequate air flow. The backpack straps are designed for easy adjustment.
