Advertise a shirt as having a a UPF of 50+ then charge $40 more for it over a $10 shirt that will do the same = scam.
There is now a whole market out there profiting from this scam.
Are major cycling apparel brands actually charging $40 more for an UPF rating, or is it just informative (and good for marketing) to mention that "btw. this fabric of ours blocks sunlight in a measurable manner"
As has been mentioned before, a tighter knit, thinner thread, higher thread count fabric will also have a higher UPF-rating regardless of material. But incidentally, fabrics which are tighter knit and have thinner thread as well as higher thread count are also both higher in quality and more expensive. And with fabric quality the price goes up exponentially for some reason. Probably because they're exponentially more difficult to manufacture and also supply/demand.
Also, I've gotten sunburn through a shirt. But never through one of my UPF50 shirt. But I'm a northener so I burn easy.
