A fabric with a UPF rating of 50 permits only 1/50th of the sun’s UV rays to pass through. Samples have been tested for UV protection at Bureau Veritas Consumer Product Services following the standard AATCC 183:200 “Ultraviolet Protection Properties for Fabric.” Features The UPF 50 protection provides reliable defence against UV radiation in compliance with standard AS/NZ 4399:2017 and is certified as CE personal protective equipment (PPE), offering a UPF rating of over 50 with 98% UV protection, though the level of protection may decrease over time. The UltraStretch technology ensures exceptional elasticity, delivering superior comfort and enhanced performance for various activities. The HeiQ Smart Temp feature incorporates advanced thermoregulation that activates in response to body heat, ensuring an optimal level of comfort. The moisture-wicking design effectively draws sweat away from the skin and facilitates rapid evaporation, making it an excellent choice for high-intensity activities.
