Hi! As heatwave scorches Europe, the second problem I’m a little afraid of (especially as someone without any melanin in my skin) is the sun. I’ve seen someone mentioning a sun shirt but trying to find real information online is very confusing, especially with EU in mind ( I see US has something called UPF) and if you are not looking for ads. Maybe someone knows something about it?
Look into “fishing” shirts. Brands that sell long sleeve breathable shirts will point you in the right direction.
Essentially, they have an equivalent minimum SPF. Usually around 15-20. Brands like HUK and Columbia come to mind but they are expensive and high end. There are many other alternatives.
