All of eclisse fabrics are certified with a UPF Factor. UPF stands for Ultra Protection Factor and is a rating given to specific fabrics for sun protection. The UPF factor indicates how much UV Radiation (both UVA+UVB) a fabric allows to reach your skin. For example, a UPF 50 fabric blocks 98% of the sun’s rays and allows two percent (1/50th) to penetrate, thus reducing your exposure significantly.
eclisse even in the clouds.
While clouds do reduce some of the sun's UV rays, they don't block all of them.
UVA rays can penetrate clouds and damage the skin. Just because it's cloudy and you aren’t feeling the heat from the sun doesn’t mean the UV Rays are not doing damage to your skin. Anytime you are outdoors for any period of time – regardless of how sunny it is – you should be protecting your skin with eclisse.
