I have been searching for this kind of sports bra for a very long time! The straps adjust by hooks on the shoulders rather than the sliders most use, this prevents the bra strap from loosening while I work out. I love that it has a 3 hook closure so it is secure, and that there is 4 different size positions for around the chest. I bought a medium and I wear it on the second smallest position and I normally wear a 32 D for bra size. So easy to put on and get off since you don't need to pull it over your head! It also comes high enough on the chest that you don't feel like the girls will spill out.
