I don’t have the highest degree of confidence in it but it makes sense to me that absorption matters more than reflection because a lot of the reflected UV will be going through the shirt and onto your skin
That’s why materials like linen aren’t as good for UV protection. They’re light weaves and let a lot of light through, still
Umm…
Reflection is just as effective as absorption. As long as the UV isn’t passing through the fabric into you, you are fine.
Look at the sun through a white shirt, then black. Which is brighter?
Gotta get that UV colored tshirt :-)
FYI there are UV absorbant tshirts, crazily practic for kids.
Skincancer.org is my source for darker colors being better protection
