The evolution of the backpack in the 20th century
The new materials and technologies have significantly changed the world of backpack design. In 1938, an American climber installed the first zipper on his backpack, which allowed for better weight distribution by changing the shape of the bag. The idea had so much success who soon after created his own company specializing in the manufacture of backpacks and other travel equipment. In 1951, another significant event occurred: California resident D. Kilty introduced a belt into the backpack design. This thought occurred to him by accident : one day , while carrying a backpack , the metal legs of the frame caught on the back pockets of his hiking pants. After a few steps, Kelty realized how easy it was to carry a heavy backpack. Okay It is worth noting that an old wooden frame was originally used, so the next step was to replace it with a lighter aluminum analogue.
The idea of replacing a tight canvas with lightweight and durable nylon was proposed by Dick Kelty himself. It all began with the purchase of camping equipment at a sale of antique military equipment. A once he was offered buy nylon of parachute , which had remained in military warehouses since World War II. Noticed that this material was ideal for creating travel backpacks, as it proved to be much lighter and more durable than traditional canvas.
In 1952, the Kelty couple founded their company, beginning to produce innovative products designed by Dick. Their backpacks HE have become popular among the famous hikers and climbers. In 1963, a group of climbers led by Norman Dierenfurt and Jim Whittaker conquered Everest using Kelty backpacks, which led to the brand's widespread fame, first in the United States and then in Europe. The models modern backpacks continue based on in the revolutionary ideas of Dick Kelty.
