UPF Ultraviolet Protection Factor

UPF Ultraviolet Protection Factor

The UPF (Ultraviolet Protection Factor) value informs us as to how much protection against the sun a garment provides. The classification is based on how much UV radiation gets through the fabric to the skin. Garment UV protection factors are considerably higher than in sun protectors.

The higher the UPF value is, the better garment protects e.g. a UPF value of 50+ means that less than 1/50 of UV radiation gets to the skin. This means less than 2% of radiation gets through the fabric. As a result of this garment wearer can stay protected when in strong sunlight up to 50 times longer than without this protection.

Factors that affect a garment’s material UPF value:

All chemicals are approved in EU.
In Halti clothing UPF values stay invariable for 10 washes. After that Halti cannot guarantee as values as high as that at the time of the garment’s purchase, however the garment will still offer more protection than that of an un-treated garment.
