This wearable sleeping bag isn't the first time someone's designed bedding you can stay in all day long — that honour probably goes to Selk. But it is the first sleeping bag you can wear that doesn't make you look like you're wrapped in a ridiculous puffy spacesuit.
At night, Doppleganger Outdoors' wearable sleeping bag entombs you in a cocoon of fibre filled polyester, keeping the cold out with sealable sleeves and a bag that wraps around your legs and feet. But the bottom half of the $US130 sleeping bag can actually be removed in sections, turning it into a long winter coat, or a shorter jacket when you need the freedom to move around. Not only is it a more comfortable approach, but you can also roll up and compress the bottom section so it's small enough to stash in a pocket, helping keep your camping kit as minimal as possible.
