Yosemite National Park is located in central California, USA. GRAMICCI was born in Yosemite, a sacred place for rock climbers.

      In the 1970s, Mike Graham, a rock climber known in the U.S. as "Stone Master" and a leader of Yosemite rock climbing, developed revolutionary details that were not available in climbing wear at the time, such as the "gusset crotch" that allows the legs to open 180 degrees naturally and the "webbing belt" that can be adjusted with one hand. In 1982, GRAMICCI's climbing pants with these unique techniques and functions were born in a small garage in California.

      The design and many details developed by GRAMICCI are the perfections of climbing pants, and many brands have adopted these details.

      The functionality developed in the hardcore climbing environment has also attracted many people for its "easy and comfortable fit" for urban use.
