Okay heat map is cool, but what does it look like? any different? Also how does it breath? Natural cotton shirts still feel the best to me. I hate Rayon. I'm interested in this because I currently live in Singapore where it's sunny, annoyingly hot and humid all year round. I'd welcome something like this when I'm outdoors. Just too light on the details.

Yeah the lack of even a regular color photo is weird.

Unfortunately this new fabric only helps with the "sunny" part (it keeps you cooler when you are exposed to direct sunlight), but not with the "hot" and "humid" part...

  If it can more effectively radiate body heat away from you it would be somewhat effective. Plus, radiant heat doesn't have to be from direct sunlight.

  Try airism from Uniqlo, I can’t wear cotton shirts without it anymore.

Looking at the pictures in the scientific article it doesn't look particularly weird, just a white cloth: https://science.sciencemag.org/content/early/2021/07/07/science.abi5484 https://science.sciencemag.org/content/early/2021/07/07/scie...

  You link to what I assumed to be a picture, got a paywall instead.

    Sorry, being under the IP address of a university removes a lot of paywalls :) Here's the images from that article https://ibb.co/1fBT3RZ https://ibb.co/1fBT3RZ https://ibb.co/tQRVqS2 https://ibb.co/tQRVqS2

      Cool. I wonder if you could turn it inside out, such that it dumps heat inwards to have the opposite effect and warm you?

        It probably reflects sunlight, not heat. So unless you shine very brightly it won't work in reverse :)

One thing I noticed is that their control was a cotton shirt "about the same thickness" as the new one. But the new shirt is "550 micrometers" thick, which is about twice as thick as a regular T-shirt. So maybe they're tilting the scales a bit to make the cooling effect seem a little better?

  What constitutes a "regular T-shirt"? I have t-shirts that are quite thin, but I also have t-shirts that are quite thick. Both I would consider regular t-shirts. At least for me, undershirts and blended material t-shirts tend to be on the thinner side while graphic t-shirts are usually heavier. I also have some t-shirts that are ridiculously thin that I think are mostly synthetics but there's no tag so I'm unsure.
