I have used Coolibar and Champion brand Vapor. They can be ordered off of Amazon. The Vapor long sleeve shirts are really cool and comfortable so far, even in the high heat. Coolibar also has a neck gaiter that helps cover the back of the neck - which is my most prone spot - and can be pulled up to cover part of face or over the ears. There is another brand called Kalily that has neck gaiter/bandanas that have more color and pattern options.
I use these for swimming in the ocean/snorkeling, as well as yardwork. Sunscreen has a lot of chemicals that often can cause cancer and hormone imbalances themselves, not to mention has to be constantly reapplied. Plus, sunscreen has been proven to be killing the local reefs. So since I live in a climate where one is exposed to harsh rays basically every time one steps outside, and we are surrounded by reefs and ocean, it is a time saver and probably better for personal health in the long run to wear these instead of applying sunscreen every few hours for life - especially given that I am someone who has very fair skin and burns within minutes (and have a weakened immune system that makes me especially susceptible to cancers). The long sleeve versions, as well as pants if you feel like buying those, have the added benefit of being cool while helping to keep off mosquitoes and other bugs.
A note that some of our beloved plants can help with the sun, both as a natural sunscreen (I haven't figured out a strong formula yet, but some of the oils are beneficial for basic SPF), and oils like Neem, CBD, and others [as well as baking soda] have been successful in treating skin cancers. There are people out there who rely only on that, and have self-reported cure/remission... but of course do diligent research to determine your own course of prevention and treatment. Not all skin cancers are the same, and not all individuals may respond exactly the same way to a particular treatment.
