Act Running Men's Short Sleeve BioPerf T-Shirt
Experience ultralight comfort with the Act Running Men's Short Sleeve BioPerf T-Shirt, designed for runners and triathletes who demand breathable performance and unrestricted movement. Weighing just 113 grams, this premium running T-shirt features exceptionally soft, silk-like BioPerf™ fabric for a barely-there feel that keeps you comfortable during training sessions and race-day efforts.
Made from 100% plant-based nylon derived from renewable castor beans, the BioPerf T-shirt combines high-performance breathability with a more considered approach to material sourcing. Producing just 2.03 kg of CO₂ – 46% less than a standard running T-shirt – it offers an excellent choice for athletes seeking lightweight running apparel with a reduced carbon footprint.
