This Waterproof Sleeping Bag Uses NASA-Grade Aerogel to Withstand Sub-Zero Temps

Although it was invented by a scientist in 1931, aerogel insulation wasn’t used by NASA until the ‘90s, when it was applied inside blankets and spacesuits for astronauts. At one time the lightest solid in the world, aerogel is also known for its resistance to extreme cold due to the gas-filled interior.

Biigloo, a new product that’s currently funding on Kickstarter, uses aerogel in a big way. Enabling the sleeping bag to resist temperatures as low as -40°F, aerogel is embedded, along with DuPont Sorona bio-fleece, inside of the abrasion-resistant and waterproof 20D400T nylon shell. Equipped with anti-snag YKK zippers, the windproof sack sports a mummy-like shape that contours naturally with your body and warms your head as well.

While this isn’t the first aerogel sleeping bag ever, with L.L.Bean testing out the tech back in 2018 on a now-extinct model, the Biigloo is indeed the most weatherproof version we’ve ever seen. With an impressive 10,000mm waterproof rating, the sleeping bag can survive torrential downpours longer than you.

Available in six colorways, the Biigloo sleeping bag can be reserved by funding the Kickstarter campaign, with early bird prices starting at HK$1,478 (~$189).
