If you've never seen or heard of the Selk'bag wearable sleeping bags before, you're getting up to speed at the perfect time. You can think of them as a one-piece pajama for adults except with the same amount of insulation you'd find in a sleeping bag, so they'll keep you extra warm at night. And now they're available in four Marvel-themed versions letting you seed some truly memorable dreams.
In a traditional sleeping bag you're left feeling completely mummified, and a trip to the outhouse requires you to first escape from your cozy prison. That's not a problem with the Selk'bag, though, because removable reinforced feet, easy access to your hands, and zippers running all over the place let you walk around and keep on doing exactly what you need to do without having to face the cold.
And now you can do it all while bearing a slight resemblance to Iron Man, Spiderman, Captain America, and even the Hulk for just $150. It's the perfect cosplay solution for comic book conventions in Alaska, Antarctica, or San Francisco in the summer. [Selk'bags via Dude I Want That]
