Pure Functional Shirt, this shirt is different from all our other shirts. Pure Functional shirt is made of 87% polyamide and 13% elastane. This high-tech fabric is developed and made in Northern Italy and has its origins in outdoor sports. Thanks to this high-tech fabric, this shirt breathes very well, feels cool (even when it is very warm) and is non-iron. The shirt masks unwanted odors and has a UV 50+ protection. Due to the elastane, this shirt has a "four-way" stretch and the body size also changes per collar size. In short, a perfect fit! (see the dropdown menu "Description" for the size chart)
