It's not the best materials, nor the most supportive, but I needed a new bra in a smaller size, and I didn't want to pay a lot until I knew what size I would wind up at the end of the exercise program. I wouldn't use it for HIIT, but it works well for weights, yoga, and low to medium impact cardio or balance training. Now that I've leveled out in size, I will probably go back to my Panache sports bras.
