Long clothing and big hats are probably your best bet. If you want to learn more you can check out the Handbook Of Natural Fibres[1], but the short version is: white dye and looser weave mean less protection, colored dye and tighter weave mean more protection. It's mostly pretty intuitive, but the dye makes a bigger difference than you'd expect. A white cotton t-shirt might have a UPF rating around 5 (1/5th the UV exposure), while a colored shirt is likely above 20. [1] https://sci-hub.st/10.1533/9780857095510.1.141. |
