Crafted from 100% recycled polyester, the Illumi Trax V2 Performance Singlet is built for hot-weather runs, track sessions, and low-light miles. The fabric has a soft, cotton-like feel with a lightweight 74g construction, breathable laser-cut ventilation, and natural stretch for easy movement. Reflective prints on the chest and back add visibility after dark. Soft, light, breathable, and made to move.
