Sports bras are still bras, they need to fit

Although many people think one sport bra is pretty much the same as another, this is not true. Just as a properly fit everyday bra can make huge differences in comfort, a little judicious research can make your active time more enjoyable. Chafing, uncomfortable movement, lack of support; all these things will throw you off your game in a heartbeat.

Fit The bra should fit firmly enough to control breast motion, but not so tightly as to interfere with breathing. During vigorous movements, the entire upper body should move as one unit, with limited bouncing of the breasts. Give the bra the jumping-jack test to be sure it meets these criteria.

Support Minimal movement of the breasts within the bra is important to reduce chafing. Larger-breasted women will probably be more satisfied with molded cups. For maximum support, look for minimal vertical (neck to navel) stretch in the fabric. Horizontal stretch is necessary to get the bra off and on easily and not interfere with breathing.

Fabric Prevent moisture from accumulating. The bra should be a blend at of least 50 percent cotton and a breathable material such as Lycra mesh to help evaporate sweat and keep odor in check. Cotton provides more comfort than synthetic materials, reduced stretch, and greater support. The bra also should be lined under the breasts and under the arms with material like CoolMax that removes moisture from the skin by wicking the sweat outward.

Seams Poorly placed seams can irritate the nipples. Cups should be seamless or at least have covered seams. Hardware like hooks or fasteners must be covered with fabric and should be cushioned for maximum protection.

Straps Choose wide, nonstretch straps for best results. In addition, a wide “Y-back” panel can help increase support. Some sports bras offer a two-hook back for an adjustable fit.

Mobility Many sports bras are shaped like halter tops. Be certain the armholes allow ample room for the unrestricted arm movements necessary during exercise and for freedom from chafing.
