Finding a proper fitting running bra is essential. Runners know that many running bras often feature seams or rough fabric that causes chaffing and irritation. Zensah understands this and has developed a most comfortable running bra. Each running bra is made with propriety Zensah fabric - meaning the running bra is thermal regulating, as well as moisture wicking. The Zensah Running Bra will help to keep dry when you go running.
