I just tried searching for these and I’m genuinely confused. Is it not just…a hoodie made of light material? I mean, surely most if not all clothing will stop you getting burnt.
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.
Interesting! I’ve never burned though a shirt but perhaps I’ve been lucky. Maybe I do need to invest in one of these…
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.
Negative, cotton is basically like wearing nothing. This user have a good explanation.
