❄️ Graphene Sleeping Bag Adapts to Cold

Hong Kong's Graphene-X is crowdfunding a modular sleeping bag system on Kickstarter. The Tardigrade Sleeping System includes a winter bag rated to -30 °C, a lighter three-season bag rated to -10 °C, and an insulating liner that can be added for extra warmth.

The bags use graphene, a one-atom-thick carbon sheet known for strength and heat conduction, combined with aerogel-filled fabric tubes. These tubes inflate or deflate based on outside temperature, letting the bag adjust insulation without adding weight.
