For pioneering innovation and eco-conscious running, the Janji Men's Runterra Bio Tee sets precedence. Extremely soft and durable, this shirt uses special technologies to maintain thermal, vapour, and odour regulation during your run to keep you comfortable and smelling fresh.  Made with Runterra fabric that is lightweight and versatile, you can throw this tee on before, during, and after your workout. Note that this short sleeve is not pre-shrunk and could shrink up to half a size.
