UV.LINE fabrics are carefully selected and receive special treatment that guarantees the blocking of more than 98% of solar radiation. All fabrics are tested and certified by ARPANSA, the Australian entity that created the standard for measuring ultraviolet protection in fabrics and that is a worldwide benchmark in measuring FPU. FPU50+ is the highest protection factor, which blocks 98% of the UV rays. All UV.LINE products have the maximum protection factor in the fabric weave, that is guaranteed for the entire lifetime of the product.
