“I love this bra I'm pretty heavy chested and I don't move it's great. I've already had 4 of my friends try this and they Are going to get one as well. I do a boot camp work out with jumping jacks m, burpies, and mountain climbers and I have no issues. I have always had to wear 2 sports bras in the past and this one is so much better bc it zips in the front.”
