This is the only activewear bra top that fits with coverage. The fabric is soft and strong. There is plenty of room for my big old titties, they are not spilling out anywhere, and the band fits well against my rib cage and it does not cut in at all! I would not characterize this sports bra as high impact and will not be running or jumping in it. For me I would say it’s medium impact, maybe because I have so much breast tissue and require much more compression for high impact. I’m happy to have found it! Usually I have to buy a cup sized sports bras but it’s nice to have one that’s less structured and more comfortable. For reference I believe I’d wear a 38H in bra sizes... if I wore them. Thanks for the awesome customer service!
