I LOVE (love, love!) my black size L zipped max support top. It relieves the dull back and neck pain that normally builds through the day at my drawing table & computer (I’m an illustrator) and if on my feet for long periods. I’d much rather wear your top to help support my lower back than the Velcro hell of my lumbar back brace from a chiropractor. Also, when I wear the the top, there’s little-to-none of the “band of steel” pain in my upper back that usually builds through the day. There’s no bra band digging under my breasts (what a relief!), my slumping posture is greatly improved, and I love how it holds my stomach in! It’s like you invented a modern “girdle” that is also remarkably comfortable!
