Provided much-needed support I haven't yet found in a sports bra. I have a large chest (36E) and my workouts consist of high intensity exercises and cardio, and I have finally found a bra that holds the girls in place. The back band has something like 6 eyelets, which may have taken a test round to get used to fastening, but the wide strap makes it really comfortable - enough to sleep in. It's also super comfortable and doesn't make all my back/armpit fat hang out all awkwardly when I have a sleeveless shirt on. Lastly, the double layer doesn't add volume to my chest (don't need that!) but ensures that your nipples aren't sticking out during a really intense workout - modesty is very appreciated here. I initially only bought one of these and a different brand to compare, but I'll definitely be buying another of this one only.
