This Polo shirt was designed to add a more sophisticated look to your tennis or golf outfit. We used our signature fabric produced with biodegradable nylon (6.6), a Brazilian pioneer technology in the world. This yarn has been enhanced to allow clothing to quickly decompose after disposal in landfills. The breakdown that before took decades to occur in nylon (polyamide generic name) now 50% already happens in the first year and it is fully decomposed after three years. It offers UV 50 protection and it's free from toxins to human skin according to international standard Oeko-Tex 100 C
