Look for "technical" fabrics and smooth seams.
A good sports bras wicks moisture from your skin. Breathable synthetic fabrics such as polyester, CoolMax, DriTek, and Lycra work much better than cotton. Also, check for smooth, flat seams that don't rub your skin raw. Sports bras fall into two categories: encapsulation bras that isolate each breast in a distinct cup, and compression bras that hold your breasts against your chest. Tests have shown that encapsulation bras offer more support for well-endowed women than do compression bras. Most bras experts steer larger-breasted women toward encapsulated bras, but everyone's different, and some women swear by the compression style.
