Optimistic Runners brings a bit more to the humble running singlet with the Layered Perforated Singlet, pairing a lightweight outer layer with a built-in layer underneath.
The outer layer is made from perforated polyester-elastane, with the holes running across the body to keep air moving as you run. Underneath, a recycled polyester layer sits close to the body, adding coverage while keeping the top lightweight and quick-drying.
