Our Space-O™ perforated singlet is engineered for trips of high intensity. The micro-holes in the fabric reduce its weight and maximize breathability while also providing an easy way to attach a race bib.

- Space-O™
Our micro jersey fabric is knitted and perforated in Italy. It naturally stretches in every direction following the body's movements while staying breathable. It's created using a laser microperforation technique called punch-out, which removes portions of fabric leaving micro-holes. This allows greater breathability and lighter weight while also providing an easy way to attach your number on race day.
