If you want to form a new company that can make radically different products for the outdoor industry, what better way than to gather together industry veterans who are also accomplished outdoors people? 

That's exactly how Mountain Hardwear® came to be back in 1993 and the innovative, radical thinking of that founding team and its employees is what drives them every day to continually invent (and re-invent) the most functional and innovative gear available. 

The company has patented their Cross Flow® tent construction, developed WindStopper® next-to-skin fabric in partnership with Gore®, and has also patented Quantum Expander® for sleeping bags - to name just a few of their accomplishments! 

Mountain Hardwear - technologically-advanced gear well suited for any outdoor pursuit.
