Cocoon

Just want to snooze in privacy for a few minutes? Need a hotel room but can't find one? Lost in the mountains without a tent or shelter? Facing a swarm of angry hornets?

Introducing the Cocoon device. You wear this neat package strapped to your waist. When activated with a button, out springs a durable multi-layered shell that you can quickly pull over your body and zip up. Has the interior of a comfortable sleeping bag, and the exterior is tough, weather-proof and water-proof. (You can breathe through small filtered holes.) Its small size and super-fast-deployment will make it superior to ordinary sleeping bags.

Plus, like a glove fits your fingers, the Cocoon has limb extensions where you can fit your legs and arms, so you can walk in it if necessary (like when you need to escape from hornets).

For those with a sense of humor, the exterior can be furry or scaly and made to ressemble your animal of choice. Choose the hairy bigfoot exterior and you'll probably scare away most predators in the wild.

Comes with a Do-Not-Disturb sign which you can switch on when you deploy the Cocoon in your office.
