Way too simplified. You don't think I gave up wearing white cotton shirts in hot climates? Of course I did, but that's because there's not enough information

Way too simplified. You don't think I gave up wearing white cotton shirts in hot climates? Of course I did, but that's because there's not enough information to judge shirts off the rack aside from the "100% cotton" label. Anyways I don't need the nitty gritty details, but there should be some sort of consumer friendly information that would make it easier to judge things. Not necessarily what the experts use.
