History
Founded in 1965 by George Marks and Bob Swanson in California, Sierra Designs played a pivotal role in the development of the modern outdoor industry. The company introduced the 60/40 mountain parka, a garment that combined cotton and nylon for weather resistance. This innovation became a staple of 1970s outdoor fashion and influenced the heritage aesthetic. The brand's technical advancements in tent architecture and sleeping bag design further established its historical significance in wilderness recreation.
