They talk about how to look for a tighter weave in the fabric, how a thinner fabric let’s the uv radiation through. This is common knowledge, where I’m from. The childcare centres send out notices about it. Do you need to be scientific about basic knowledge? This is basic stuff, buddy.
Most clothing is UV blocking. That’s why farmers tans exist.
Not as much as you would think, and especially less nowadays with companies cheapening out on quality.
As long as there are no holes lol
The uv radiation permeates the fibres, even when there aren’t holes that aren’t supposed to be there. It’s dependent on the thickness of the weave. Fun new fear to unlock. https://www.solbari.com.au/blogs/solbari-blog/can-uv-go-through-clothes
Bruh they are saying a cotton t shirt, literally your arms exposed so of course it’s very low uv coverage. It’s not a very scientific article

Do not trust that close to the equator. It will not work.
I live at high altitude where the UV is stronger than anywhere else. Clothing still works. Heck, even a light shawl works.
