Jgppe Sport Bras for Womens Front Closure Zipper High Impact Shape Wicking Shock-Proof Bras for Running Workout

My first impression was that the bra is comfortable. The second was that it is not truly a "High Impact" bra. This might be enough suppport for someone who is not busty, however if you are busty, you will not be able to jump around without some bounce. You could still wear it for some high impact activities and be comfortable, but you will get bounce. They could have probably fixed this by making the straps adjustable, however I also think it's partly due to the material, which is the reason it is so comfortable, that makes it not as supportive. It has some stretch, though not as much as other bras I have tried. All in all, in a pinch, you could probably still wear it for high impact activities, but won't be as supported as with other bras. It is a great buy for the money though. The only other thing I'd mention about it is that if you are looking for a smooth look under your shirts, the zipper does kind of ruin the seamless look.
