Halti offers a broad selection of UV-protective summer clothes with up to UPF 30-40 +. The UPF of Halti clothes is based on the weaving technique of the fabrics, without any chemical treatment.

Health and well-being is something we highly value at Halti. We promote these by encouraging people to enjoy the outdoors all year around. When spending time outdoors especially in spring and summer, protection from the sun's harmful UV radiation becomes an important factor.

The sun emits different types of UV light, including ultraviolet A (UVA; long-wave) and ultraviolet B (UVB; short-wave) rays. Both UVA and UVB reach the earth and play an important role in premature skin aging, eye damage (including cataracts) and certain skin cancers. It is important to know that 90% of the UV light penetrates through clouds so that people at risk need to protect themselves every day, whatever the weather.

The Ultra Protection Factor (UPF) rating is based on the amount of UV radiation that permeates the fabric and reaches the skin. The higher the UPF figure, the more protection the garment provides – UPF of 50+ means that less than 1/50 UV rays reaches the skin, or that less than two per cent of radiation permeates the fabric.

A UPF of 15–24 gives good protection, 25–39 very good protection and 40 or 50+ excellent protection.

The UV protection in Halti clothes remains in up to 30 washes.
