The SPF (sun protection factor) measures the amount of UVB absorption, but there is no method of reporting the UVA absorption. The only way to determine if a sunscreen protects against UVA and UVB radiation is to look at the ingredients. A good broad-spectrum sunscreen should have an SPF of at least 15 and contain avobenzone, titanium dioxide, or zinc oxide.[1]

Here are SPF ratings for some garments:

  • Nylon Stockings - SPF 2
  • Hats - SPF 3-6
  • Summer-weight clothing - SPF 6.5
  • Sun-protective clothing - up to SPF 30
