The origin of outdoor folding bags can be traced back to the invention of mountaineers. When mountaineers reach the final camp before attempting to summit, they cannot carry heavy and cumbersome large backpacks anymore, hence the need for such a bag. The requirements for this type of bag are:

1. Ultra-lightweight, minimizing the weight of the bag itself.

2. Folding and Storage: When folded, the volume is very small, and it can be placed in a large hiking backpack during the ascent, making it convenient to carry.

3.25 liters of capacity, suitable for holding a certain amount of beverages, insulated clothing, and life-saving equipment.

Section 4: A certain level of water resistance, the fabric is quite durable and resistant to tearing.

5. Shoulder-carrying, completely frees both hands 6. Color should be bright and eye-catching

Therefore, this type is also known as a summit bag.

 Now, there's a problem with this backpack on the market. It's being sold as something it's not. It's made of polyester, but they boast it's made of nylon. It's not even waterproof, but they boast about how well it's waterproof. We want to remind everyone to be careful and check it carefully.
