This sleeping bag that looks like a giant pair of blue jeans, I don't know which part of their ludicrousness to tell you about first. OK, the obvious: this is a giant blue jeans sleeping bag (Ludicrous Part 1). It sleeps two people, one in each leg, or one person in one leg, and one person dressed up as a furry polar bear wearing a sleep mask in the other leg (Ludicrous Part 2).
Next, the official name of the giant blue jeans sleeping bag is The Super Big Wrapped in Warmth Happy Furry Jeans Sleeping Bag by Felissimo (Ludicrous Part 3). It costs almost $700 (Ludicrous Part 4).
The only non-ludicrous thing about the giant blue jeans sleeping bag is that it, like all of these weird products, is from Japan.
