So I'm on a medication for the next several months (through the month of May) that has a precaution of avoiding sun exposure. I'm looking for a long sleeve bike jersey that carries a reasonable UPF that's not made from a thermal material. I'm looking for material that's light like a regular short-sleeve jersey.

I've found a white long -sleeve jersey on Aerotech Design's website, but the lack of color is a minus. They have some other long sleeve jerseys, but their website admits they don't have an UPF rating for the material.

Anyone have a recommendation? I'd prefer to not have sun sleeves, but maybe ultimately that's the way to go. I'm 6' 2" tall, 175 pounds, and my arms are on the skinny side. In a short sleeve jersey, my favorite, size-wise, is a "large" from Primal Wear. Thanks!
