By changing the traditional carrying method and backpack straps, the deltoid muscles of the shoulders are used as the load-bearing points of the backpack. Through the combination of shoulder pads (1), shoulder pad air cushions (2), three-way backpack straps (3) and other accessories, the
vertical load-bearing mode of the trapezius muscles of the shoulders is changed to the three-way load-bearing mode of the deltoid muscles of the arms. Three key innovative technologies are used to avoid the trapezius muscles, which are prone to fatigue when under load, and to transfer the weight of the backpack to the deltoid muscles of the shoulders, forming a three-way
load distribution carrying
system on the shoulders and chest. This makes the trapezius muscles of the shoulders no longer feel sore when carrying heavy objects, allowing us to carry heavy items for a long time. When carrying more items and outdoor equipment such as tents during outdoor rescue, field research, hiking, etc., it feels easier, the carrying time is longer, and more items can be carried.
