The idea of coffee clothing may sound a bit ridiculous, but hold on a second here, there might be something to this. A company called Virus Action Sport Performance has recycled spent coffee beans, processing them into fibers that are used to produce a warm base layer for cold weather activities. You do still need a wind break layer on top, but as long as you’re using these as a true base layer and not solo, you can expect them to provide around a 10 degree boost, according to the manufacturer. With the ski season almost over, I might have to wait until next winter to give them a try. You can find them at this link.
