Zelos Singlets were developed to help you to reach optimum performance as both a first layer in colder weather conditions & as your choice of garment for those warm summer runs. Fit Sitting close to the body, the Zelos Singlet is finished with anti-chafing flat seams to optimise comfort under intense resistance. Performance Fabrics Built for performance, the Zelos Singlets lightweight fabric holds naturally wicking properties to keep you dryer for longer. Mesh panels are featured under the arms to increase ventilation flow & breathability. Reflective Finishes The Zelos Singlet features a reflective dhb logo & reflective tabs finished with a fluro yellow print to aid visibility in low light conditions.
