There aren't many people in the world who conduct body heat, which means that for most of us humans, we wear jackets. It's OK to admit this, because the truth is, even Ubereem wears jackets and he has proven to be the next iteration of humanity's evolution through unparalleled striking and grappling skills and looking like the Incredible Hulk. Now that we've given you a strong point of reference in Alistair Overeem, K-1 World Grand Prix Champion 2010, DREAM Heavyweight Champion and former Strikeforce Heavyweight Champion (never lost the title, was fired for being too awesome) and possibly future UFC Heavyweight Champion, and proved that yes, he wears jackets.
So to explain that Columbia Sportswear, a company that is known for making quality winter gear and being one of the few industry standards, went out and found a guy who produces immense body heat with his mind and can survive arctic temperatures in nothing but a pair of shorts, well, you'll probably not believe it. So watch and learn. Columbia has developed a new electric jacket. Yes, it is literally goddamned electric, and it warms you up at the touch of a button. All in all, that is a whole love easier than mentally preparing yourself to "not be cold" while in sub-zero temperatures.
