When does cold actually mean hot? If I'm ever stranded in a winter storm, all I'll need would be shirtless So Ji Sub wearing Marmot survival gear. Take that, Shirtless Rain and Shirtless Lee Dong Wook! Let's check out our man So Ji Sub's new commercial and photoshoot for Marmot's fall and winter wear. You just might wish for cooler, much cooler, weather to come soon.

Marmot is an American outdoors clothing and sports good company that was originated on the idea of two college students who were climbing on the glaciers in Alaska. The company rose to fame after it designed jackets for the movie The Eiger Sanction, starring Clint Eastwood. Marmot was officially established in 1974 and will be celebrating its 40-year anniversary this year.

Here's the new commercial starring So Ji Sub:
