Camping can be tough. Having to deal with the wind, the rain, the cold and the possibility that a stray and angered bear might try and get into your tent can make it a difficult experience.
But we've never heard of anyone being caught up in a tornado while they're setting up their stove and camping chairs. Nonetheless, this hasn't prevented inventor Steve Anderson deciding to design a sleeping bag which can withstand pretty much anything.
The Tuuli Armor Tornado Shield has been designed to shield those inside it from debris and shrapnel that are flying at speeds up to 260mph. It's made of ballistic nylon used by the military and, as the video shows, it comfortably deals with shards of wood, metal (specifically, a 5-ounce, 3/8-inch round steel rod) and glass that are hurtling around. It doesn't have air holes, but it is, apparently, still breathable. We're not sure how that works, but we'll go with it.
It's currently for sale on the Indiegogo website, with a purchase costing $320; ultimately Anderson aims to raise $105,000 to enable the mass production of the item.
Now, if only they could make it soundproof to stop the noise of bongo players at festivals at 4am then you'd truly have the ultimate sleeping bag.
