Sierra Designs was founded by George Marks and Bob Swanson in 1965 in Richmond, CA. They wanted to design outdoor equipment that would enhance your experience in the rugged outdoors. Sierra Designs products have been tested as they've traveled to the highest peaks, held up in 230 mph winds, and withstood unbearable downpours. Sierra Designs moved to Emeryville, California, in 1994. Today, they have several partners worldwide and in the USA you can find them in Louisville, CO with warranty and repair in St. George, Utah. Many innovative products have come from Sierra Designs, for instance, they have a sleeping bag tailored to fit a woman's shape and warmth needs. Another patented and exclusive design from Sierra Designs is the Clip-Locks that locks poles at the intersection to improve tent strength by 60%. The Sierra Designs Hercules Tent is wind tunnel tested and has been on expeditions. Its two-pole design provides the simplest set-up available in extreme conditions.
