My boobs are huge - as in 38H. Finding a sports bra that will hold those suckers down has been near impossible.  I bought my first one of these, along with the Enell running bra.  I hate the Enell.  All of those hooks make my hands cramp and when I teach Zumba, by boobs look like they are doing a Cuban Salsa side to side.  What I like about this bra is that it has cups and a sturdy underwire.  My older bras are two years old and the underwires are still intact.  It also has a second covering, like a shelf bra.  This keeps everything in place.  This bra is comfortable enough and holds me up enough that I wear it every day, not just for sports.  The downside is that it does give a uniboob.  However, even with my 38H's from Fantasie, by the time I put a shirt on over these monsters, it's almost uniboob. It also comes up rather high up front (good for keeping the girls down) which means that I can't wear it with some tops.  Again, a small price to pay for keeping my junk in place.
