Who knew that sun protection could be washed right into your clothes? Not me, obviously. They say it won’t change the color of your clothing. Clothing that apparently may not be shielding us from the sun like we thought.
For example, a typical white T-shirt is rated UPF 5. A single treatment with Rit Sun Guard is said to boost the t-shirts rating to UPF 30. UPF (Ultraviolet Protection Factor) describes the capability of the fabric to prevent UV rays from reaching the skin. It is relatively equivalent to SPF ratings for sunscreen.
Wow. Again, who knew? And I thought it was best to put the kids in a thin white t-shirt outdoors.
