Ultraviolet Protection Factor

Why should you care about UPF?

Ultraviolet radiation, UVA & UVB rays from the sun are primary causes of skin damage, wrinkles and skin cancer.

This year, one in five people in the U.S. will develop skin cancer. And, there will be more new cases of skin cancer diagnosed than incidences of breast, prostate, lung, and colon cancer combined. 

Many people are familiar with SPF factors as a guide to sunscreen UV protection. Did you know, UPF factors indicate UV protection provided by fabric and clothing?

SPF (Sun Protection Factor) suggests the length of time a person can withstand the sun before getting burned. A typical sunscreen lotion (rated SPF 15, 20, 30) does not block UVA rays and must be reapplied regularly, usually every two hours.

UPF (Ultraviolet Protection Factor) is used in reference to sun protective fabrics. It indicates how much of the sun's UVA and UVB rays penetrate a garment and can reach the skin for as long as the fabric is worn.

Sansol™ is Sol La La's exclusive fabric. It is UPF rated by an independent test lab according to the AATCC183-2014 test method. Sansol™ blocks 97%+ of UVA and UVB rays from reaching the skin. By comparison, a typical cotton T-shirt blocks only 20% of UVA and UVB rays - even fewer when it's wet.
