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+!
