The On Performance Bra is a medium-support sports bra built for running and gym work. It uses a nylon, polyester and elastane blend with mesh panels for breathability and moisture wicking, and it pulls on with a racerback and adjustable straps. It suits runners and gym-goers who want a light, breathable bra rather than a high-impact compression piece. Against high-support bras from running specialists, it trades maximum hold for comfort and airflow, so it fits moderate workouts better than long-distance or high-impact training.
