Though it seems like something out of an episode from The Simpsons , the Cooline vest is an actual product. The German company put out a press release citing projections of global warming increasing the temperature by two degrees, and touts a vest that evaporates sweat as the answer for personal protection.

That's right, global warming might kill you, so you had better by a cooling vest. Per the press release:

"According to one study from the Kiel Institute for World Economics (IfW) and the World Wide Fund for Nature (WWF), the number of heat deaths would increase by 5,000 to 15,000 per year if adaptation measures are not taken."

These groups probably meant don't drive so much or turn off the lights as a counter measure, not buying a vest to protect from overheating.
