The Solar Protective Factory had The International UV Testing Lab independently test the Genuine SPF®  100% cotton white T-shirt against 2 of the top selling 100% cotton white t-shirts.  The results undeniably show that the Genuine SPF® T-shirt provides top-rated UV protection over it's competitors -- at about the same cost!

T-shirt #1 allowed almost 7% of UVA and 8 1/2% of UVB to be transmitted through the fabric and achieved a UPF Rating of 10. 
T-shirt #2 allowed over 13% of UVA and over 15% of UVB to be transmitted through and achieved a UPF Rating of 5.

The Genuine SPF® T-shirt allowed only 1.65% of UVA and 1.3 % of UVB to be transmitted through and achieved the highest possible UPF Rating of 50+!
