The North Face’s prototype ‘Moon Parka’ coat is made of synthetic spider silk

By Ed Oswald November 18, 2015

Because it’s one of the world’s stretchiest and strongest materials, spider silk has long been considered the holy grail of textiles. If we could figure out a way to mass produce it, we could make some of the strongest ropes and farbrics the world has ever seen. The only hangup is that, so far, no one has been able to successfully harvest real spider silk — mainly because spiders are a bit competitive and will eat their rivals to stay dominant.

That’s where a Japan-based biotech firm Spiber comes in. The company has been successful in creating a manufacturing process that allows it to mass produce synthetic versions of spider silk while still keeping its attractive properties. North Face took notice of Spiber’s work, and the two companies recently collaborated on a new jacket called the “Moon Parka,” a prototype of which is now being shown at events across Japan.

Spiber uses microbes to produce the synthetic silk for the jacket. The microbes produce special proteins, which Spiber then purifies until they becomes a powder. From there, the powder is squeezed through syringes to be spun into threads, according to Popular Science.

A total of 656 different microbe variations help to process and produce the final textile, which Spiber has dubbed Qmonos — the Japanese for spider web. By using microbes to produce Qmonos, Spiber is also addressing another chief complaint of the textile industry: its notorious pollution problem. With a microbe-centric production process, the company believes it can avoid using toxic chemicals that are harmful to the environment.

The Moon Parka is only the beginning, though. About 250 different thread types of Qmonos will be available when the textile becomes commercially available next year, Spiber says. An exact date for the release of the jacket is not yet known, but it’s expected to come out some time in 2016.

Digital Trends’ Top Tech of CES 2023 Awards

Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

Digital Trends’ Tech For Change CES 2023 Awards

Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.
