If a performance gilet is what you're after then the 2XU vest fits the bill.
Extremely light, it packs easily in your rear pocket. Although it's mostly black, generous reflective trim makes sure you're seen when it counts. The zips on the vest we tested were stiff for even two-handed use.
The mesh back panel suits higher intensity workouts and the chest and shoulders are windproof. A cool feature is the MP3 cable routing, however the rear pocket will not fit much more than one item. Although a snug fit, the cut around the hips is not women specific, which means the material bunches around your waist.
