It's Derelicte come to life!
On Sunday’s episode of GIRLS, Hannah donned a silly looking hooded sleeping bag, but apparently it's a real thing.
The $130 Napsack is just like a sleeping bag, only with zippers for your arms and a cinch tie at the bottom, so you can be snug as a bug or walk around and look ridiculous.
Even the people on The Today Show love it!
Ch-ch-check out the video (above) to see The Napsack in action!
