It has great support, no bounce or jiggle, and is really comfortable.
I laugh at bras sized S, M, and L so I jump on sports bras with band and cup sizes.
I could wear this bra all day! As another reviewer stated, the material is thinner than my other brand, but it's not a fault in my opinion.
The mesh at the back is supportive and holds together well, so once it was on I was not afraid that it would all burst open.
