I bought this becuase it said high impact, and was hoping it would help with the pain after working out. When it came in the mail and I opened it- the tag said Medium Impact. However, with that said- it still works very well!! Ive not had any more pain after working out- even now that Im pregnant and am very sore as it is. I love the look, its like a real bra but for working out. It seperates everything so you don't get the uni-boob. The fit is great! Very happy with this purchase!!
