After reading all the rave reviews about this item, I was certain that this was going to work for me. It did not for the following reasons:

1. The craftsmanship is HORRENDOUS for a $70 undergarment. I received small cuts near my left shoulder blade due to either the poorly sewn "sharp" seams or rough plastic strap adjuster. It poked me while at rest and scratched me while in action. I could not return as I had already discarded the box.

2. Unflattering style; style and cut gave me some "pointy" appearance

3. Not ideal for short women. I had to adjust the straps to the shortest length to make it stay on my shoulders. I would have needed additional strap adjustability to provide more support during high impact.

On a good note, it did provide adequate support in 34B while not appearing over-constricting.  It was highly breathable but it was hard to notice as it was tearing up my skin near my left shoulderblade. I will never purchase this brand again. (I have since discovered an excellent and flattering high impact bra at that wonderful Canadian yoga retail store...)
