Just like with any bra, workout bras with zippers come with some potential issues and annoyances. Because most front-zip sports bras are made with extra padding and higher necklines, they can cause even more irritation and boob sweat, which is a big nope. You may also find that some have finicky zippers that slide down mid-workout or those that are so tight and constrictive that you feel like you’re strapped into a corset. But when it comes to coverage and comfort, these bbs can’t be beaten. http://www.alianduo.com/women-s-bra/women-s-zipper-sports-bra/
