Story
The lightweight concept originates from the demand for reducing backpack weight in outdoor sports. Alpine mountaineering emphasizes independence, lightness, and speed. American long-distance hikers need to complete an extremely long route in one go, which encourages people to find ways to reduce their weight. Camels and machinery cannot completely solve the problem of carrying weight, and more often than not, humans need to bear the weight themselves. Therefore, reducing the weight of backpacks has become an inevitable demand, and the concept of lightweight has emerged.
Conclusion
From World War II to the 1980s, outdoor lightweighting was in its infancy and exploratory stage, and many well-known outdoor companies such as TNF, Marmot, Patagonia, and Osprey emerged during this stage. After the 1990s, a complete concept system of lightweight was formed and spread. After the 21st century, lightweighting has truly developed, and more and more people are exposed to this concept. The market for lightweight outdoor equipment is also increasing.
