The story
Mountain Hardwear was founded in 1993 in Richmond, California, by a small group of former employees of Sierra Designs led by Jack Gilbert. Soon after, Mountain Hardwear's first sponsored athlete, Ed Viesturs, the first American to climb all fourteen 8,000 meter peaks, helped develop several of the company's products.
