Many materials like cotton will let sunlight through quite readily, especially when thin or wet. A sun hoodie has 50+ UPF. A cotton shirt that has a similar low thickness will have a mere 5 UPF, making it basically worthless for sun protection. Sun hoodies also often sport features like vents to catch breezes.
It might just depend on the UV index where you’ve been outside. If you’re in a high latitude area, you’re not going to have that much exposure through all but the thinnest of cloth.

Interesting! I’ve never burned though a shirt but perhaps I’ve been lucky. Maybe I do need to invest in one of these…
