Comment on Why can't I apply SPF50 sunscreen twice to get SPF100 protection?

The store increases the price because people will pay more for higher number. You can get spf 80 or 100 cheap elsewhere.

Light clothing, hats are SPF infinity without toxic chemicals. Zinc or titanium cremes work best.

You still need to pay attention to the weave density and thickness. That "infinity" falls somewhat if you're wearing the clothing equivalent cheesecloth.
Source: Once got a severe sunburn on a relatively overcast day through a t-shirt that I soon learned hadn't been thick enough.

Light clothing and hats are absolutely not spf infinity.

Be aware light clothing can still transmit enough light to burn. My bullshit test is “can I look at the sun through this fabric or does it hurt?”. It’s a little conservative, but it’s good enough for me if I plan to be out for 8 hours. I actually just got burned shirtless last week on one side. With a light, black, sports shirt the next day, I was in mild burning pain when the sun hit my burned side. It wasn’t just heat, as lifted the fabric off my skin still hurt the same.

Not a hat guy, and its too damn hot to wear more clothes. Sometimes I see locals wearing puffy jackets that have fans blowing on the inside, but that seems too cumbersome.
