There actually is an engineering side to this called A-POC. But first, all the comments in both threads are kind of bizarre. Issey Miyake (who is not alive) is a famous Japanese high-end fashion designer famous for pleated designs, dance costumes, impractical appearing dramatic but unique products.
Personally I have no interest in it but to clarify just google "Miyake piece of cloth" or read the Design Boom article here:
https://www.designboom.com/des...
Or as google summarizes, "Piece of fabric" refers to A-POC (A Piece of Cloth), a revolutionary Issey Miyake project that uses computer-driven machines to create garments from a single piece of fabric. Miyake makes all kinds of wardrobe from this process. Designboom has covered various projects under this concept, such as a collaboration with Apple on a 3D-knitted "iPhone pocket" and an exhibition with Nature Architects exploring heat-reactive fabrics. A-POC was launched in 1998. It was developed by Issey Miyake and Dai Fujiwara with the goal of streamlining production. An industrial knitting or weaving machine is fed a single thread and programmed to produce a single, continuous tube of fabric. Seams are pre-woven into the fabric, and the customer can cut along these lines to create individual garments like dresses, shirts, and socks. This process minimizes fabric waste and allows for mass production of varied clothing items from a single, seamless piece of cloth. The concept continues with the brand A-POC ABLE ISSEY MIYAKE, which explores the technology's potential beyond clothing. For example, a 2025 collaboration with Apple, reported by Designboom, resulted in the "iPhone Pocket," a 3D-knitted wearable accessory. Another project collaborated with Nature Architects to develop "Steam Stretch" fabric that contracts when exposed to heat. Designboom has also covered exhibitions related to the A-POC concept, such as "Weaving Becomes an Act of Illumination" which explored creating fabrics with tonal gradients by varying weave density, and the "A-POC ABLE ISSEY MIYAKE & atelier oï" installation that showed a single piece of cloth can be used for both clothing and lighting.
So calling the product a "sock" is pretty much the most pejorative, stupid take on this and reflects exceedingly badly on anyone who repeats it.. unless that's what the Miyake or Apple people are calling it, kind of doubt that, but at least they know that it is a 3D automated tubular knitting computer output and not a fucking athletic sock. Anyway google and there are a lot of articles about it.
Looking at the PR, the picture of the iPhone peeking out from a beige carrier actually suggests it is quite a luxurious piece and the only photo in which it looks good. It suggests that the woven fabric likely delivers a very satisfying soft tactile sensation, which might outweigh all other considerations for many people once they touch it. The post shows the carrier as being able to knot itself around the strap of a handbag (Miyake's famous Baobab design using articulated triangles.. which is so popular now it is a little cringey). It is being launched at just Apple's premier addresses, probably every Baobab owner would be buying a MacBook so I get that.
Anyway, this is just a fashion accessory for people rich enough to be able to afford a mid to high range MacBook (already several thousand dollars). The colors are intended to be chosen apparently depending on whether your Baobab bag is black or white themed. Personally I don't really think most colors match, or even go well with that bag, and I don't have any desire for the carrier itself. But I expect a lot more people would buy it than the 24K solid gold Apple Watches that I thought were finished, but now I found something like on leronza.com which has full gold bracelets attached to them.. sheesh. More than I even wanted to know.
Anyway this is the only post on two threads that actually knows what this thing and A-POC are and is not belittling people for spending $200 when they probably already have spent $2000 to $8000 on a MacBook. Though when I get done buying my new tricked out MBP with 128MB RAM for gpt-oss-120B I will not be having money left over for *any* luxuries for a loooong time.
