The closure is this weird half hook & eye plus half halter sports bra closure. I have to get help to close the bra. It is soooo incredibly insane. But it has taught me a lesson - don't buy it if it has a major functionality issue. The problem is I was desperate for a high impact sports bra and the price was great. Better options are the Champion Women's Spot Comfort Full Support Bra and Champion Women's The Smoothie Bra. They have better closures and better support too.
