UPF stands for Ultraviolet Protection Factor and indicates how much of the sun's UV radiation is absorbed. Many companies have their sun protective products independently tested to determine the UPF Factor. A fabric rating of 50 (the highest) will allow only 1/50th of the sun's UV rays to pass through.  This gives you 98% protection against UV rays.
