Eclipse Sun Sleeves block both UVA & B rays, unlike sunscreen

Posted by Elise Champe on

Did you know that fabric is attributed a UPF rating which is based on both UVA and UVB protection whereas a sunscreen's SPF rating only tests protection against UVB rays? This is a very important distinction.  When you wear Eclipse Sun Sleeves you can rest easy knowing you are protected from both UVA and UVB rays, but this is not the case with sunscreen. 

UPF 50+ Eclipse Sun Sleeves feature high performance fabric technology. This performance fabric offers unrivaled sun protection, moisture control and cooling.

UPF Rating Protection Category % UV radiation Blocked
UPF 15 – 24 Good 93.3 – 95.9
UPF 25 – 39 Very Good 96.0 – 97.4
UPF 40 – 50+ Excellent 97.5 – 98+

As you can see from the above chart a rating of UPF50 means that 97.5-98% or more of UV radiation is blocked. And to be more specific UPF gauges a fabric's effectiveness against both ultraviolet A (UVA) and UVB light.

Again, an SPF number pertains only to a sunscreen's effectiveness against UVB rays, the sunburn-causing segment of the ultraviolet spectrum.
