Plus size sports bras provide the comfort and support you need for exercise and athletics, from low-impact activities like yoga through high-impact sports. Key features are encapsulation and/or compression to keep breasts from bouncing and to provide maximum support. Look for bras that have full-coverage and built-in support, like an inner sling that surrounds breast tissue and a wide, flat underband. Some styles have molded or 3-part cups. Wide straps are a key feature of plus size sports bras; they are often cushioned for comfort. For great back support, look for sports bras with racerbacks, leotard backs or full backs to enhance posture. Modern sports bras are also made of breathable fabrics with wicking properties to keep skin cool and dry. Plus size sports bras range in size up to a J cup.
