Mountain Hardwear is an outdoor apparel and equipment brand founded in 1993 by a group of former Sierra Designs employees in Richmond, California. Now a subsidiary of Columbia Sportswear Company, Mountain Hardwear designs high-performance gear for climbing, skiing, hiking, and camping, with a strong focus on alpine and technical applications.
The brand product line includes technical outerwear, insulation layers, base layers, hiking pants, tents, sleeping bags, and backpacks. Mountain Hardwear is particularly well-regarded for its Ghost Whisperer down jacket series, which has become an icon of ultralight insulation, and its Trango tent line designed for high-altitude expeditions. The company sponsors professional climbers and mountaineers, and uses their feedback to refine product design. Mountain Hardwear also maintains a commitment to responsible sourcing, including RDS-certified down and bluesign-approved fabrics.
