How does it work?
This fabric is using UV-Cut fiber that could isolate UV ray and reduce thermal transmission to provide excellent skin protection and comfortable cool performance.
This high-tech fiber is washable and sustainable. The amount of “Ultraviolet Protection Factor” (UPF) indicates the time length of a garment protects from solar radiation.
Prevent direct sunlight and damage to the skin.
Technically, a garment with UPF 1 that means users will be protected from sunlight for about 10 minutes. If you are wearing a garment with UPF 20 that means you can stay in the sun for 200 minutes (Approx. 3 hours) without any problem. Therefore, for people who have to stay outdoor all day long would need to wear UV-Cut functional clothes with UPF 40 at least.
UV-Cut fabric has 3 ratings, based on the different UPF (as the table below), due to different fabric structures and covering rate will affect the heat insulating ability and UV protection.
