I’ve always struggled in finding sports bra where my boobs will not fall out. When I buy one in size small, usually my girls will fall out from the top. When I buy a size medium, the ladies slip from under hahaha. But this sports bra, I feel comfortable and don’t have to worry about my boobs falling out at all and I can still feel sexy with the open back. I also love that the band on the bottom is wide, depending on some workouts I do, the band does flip but it doesn’t bother me too much. I just did the energy booster workout video and unfortunately, I don’t feel like the bra is supportive enough where it’ll hold my boobs from jumping way up and way down when doing the butt kicks. Maybe cause of the open back? But when doing jumping jacks, it was comfortable enough for me. Overall, for girls who are super big busted like me, I think this sports bra is good for doing various activities but not ones with super fast movements like butt kicks and jogging. Unless you don’t mind feeling your boobs up and down within your bra.
