When a climber encounters a mountain disaster, a mountaineering backpack becomes his emergency survival gear. The causes of mountain accidents often include getting lost in the mountains, becoming trapped, or experiencing inadequate warmth during the night, leading to the risk of hypothermia. Therefore, the backpack combines a quick on/off raincoat function to keep the body dry in dangerous situations. The backpack can also serve as a rescue blanket to maintain body warmth while awaiting rescue.
