I'm a 44DD and participate in hardcore cardio fitboxing several times a week. I have a stack of sports bras that I wear - none of them really doing the job - I dread the running and other jumping exercises because of the bounce and pull. This bra is completely different and does exactly what is says it does and the reviews couldn't be more accurate. I've told all my girlfriends and several of that have placed their orders. I'm jumping over to the order page and ordering 2 (at least) more.
