UPF (ultraviolet protection factor) represents the ratio of sunburn-causing UV without and with the protection of the fabric, similar to SPF (sun protection factor) ratings for sunscreen. While standard summer fabrics have UPF ~6, sun protective clothing typically has UPF ~30, which means that only 1 out of ~30 units of UV will pass through (~3%).

The ultraviolet protection factor (UPF) is a similar scale developed for rating fabrics for sun protective clothing. According to recent testing by Consumer Reports, UPF ~30+ is typical for protective fabrics, while UPF ~20 is typical for standard summer fabrics. [84]

He draws from conversations with scientists and experts within the food industry , and calls attention to the failure to rigorously state conflicts of interest in ...
For clothing, the ultraviolet protection factor (UPF) represents the ratio of sunburn-causing UV without and with the protection of the fabric, similar to sun protection factor (SPF) ratings for sunscreen. [citation needed] Standard summer fabrics have UPFs around 6, which means that about 20% of UV will pass through. [citation needed]
