This is a standard racerback compression bra that is best used for your highest-impact runs if you are an A or B cup. Mobility and comfort are not this bra’s strongest features, although it ranks high in support.
Comfort I have to be honest: comfort was definitely not the Airy Racer’s strong point. The fabric is very rough and restrictive, particularly around the shoulder straps and chest band. After one long run, I experienced significant chaffing in both areas.
Fit/Mobility The sizing does come in band and cup ranges, which is a major plus. Beyond that, there is no option for further fine-tuning in the chest band or straps. The Airy Racer restricted mobility quite a bit due to the roughness and tightness of the material. Activities that require a high level of movement are better suited to more supple styles like the Athleta Tempo Seamless Bra Top or Lululemon All Sports Bra.
Functionality The design is your standard over the head, pull-on style. There are no fancy bells and whistles here.
Support As a 34B, I thought the Airy Racer’s racerback/compression style provided ample support, even for my super high-impact stair workouts. For larger busted women, check out other styles in New Balance’s new line such as the Seamless Genius II.
Breathability The Airy Racer provides breathable mesh panels on hotspots such as the back and sides. A “keyhole” above the band in the back also helps prevent excessive moisture build-up. The remaining polyester/lycra fabric – although it wicked sweat well – got rather steamy on long workouts.
Value At $38, this is a good value if you are a serious runner who doesn’t need any fancy features, but there are more comfortable bras even at this price.
