UPF 50+ means that you can increase your skin's own protection by a factor of 50. With iQ-UV 50+ clothing, you can stay in the sun 50 times longer than without protection. Of course, only the parts of the skin covered by the UV-protective clothing are protected.
Example: If you are skin type 2, you have a self-protection of about 15 minutes without damaging your skin. With iQ-UV 50+ you are perfectly and safely protected for 50 x 15 minutes and can enjoy the sun all day.
