Perforated microjersey tank top, designed to support high intensity outings. Weight 75g. The perforated mesh fabric is knitted and perforated in Italy. It naturally stretches in all directions following the body's movements while remaining breathable. It is created using a laser micro-perforation technique called " punch-out" , which removes parts of the fabric leaving micro-holes. This allows for better breathability and lighter weight, while also providing an easy way to attach your number on race day.
