Fred Gregory is a living legend. The first Black American to command a space flight, he also flew 550 combat rescue missions in the Vietnam War. Now, you can wear a hoodie that receives his endorsement.
To put it bluntly, OROS makes fancy clothing. In June, it teased a new “mystery material” it said would mark an apparel revolution.
Meet the C41 Flight Jacket. Using the brand’s SOLARCORE aerogel fabric (which started as NASA technology), the C41 isn’t just warm, it’s also waterproof. And OROS designed its insulation pattern with body mapping to optimize breathability and protection.
Enter Fred Gregory, who’s piloted a spacecraft in orbit three times and logged over 7,000 hours of flight time. OROS tapped Gregory to consult on C41’s design. He also hand-signs an individually numbered certificate of authenticity with each limited-edition jacket.
How cool is that? Here’s a look at the futuristic duds.
OROS SOLARCORE: Spaceship Insulation

The key insulator in OROS’s C41 fabric actually insulates spaceships. NASA first developed aerogel to protect astronauts inside spacecraft, where the outside temperature plummets to -450 degrees F.
OROS took aerogel and tweaked it, combining it with flexible foam designed to be warm but not bulky, landing on a proprietary tech it calls SOLARCORE. We’ve seen this in puffier jackets, but the iteration in a soft hoodie appears to be new.
C41 uses the technology to create what OROS calls “the most scientifically innovative outerwear in the galaxy (as far as we know).”
The veracity of that claim notwithstanding, the non-bulking factor is very real: OROS claims 2 mm of SOLARCORE insulates as well as a typical down or synthetic puffy. As applied to the C41 Flight Jacket, it’s designed to hug you in the right places with body mapping and move with you with a four-way stretch.
