I love this bra.  For larger chested women like myself it's really uncomfortable to run in a normal bra.  And lots of bras are advertised as "sports" bras but so far none of them have ever really worked for me.  This bra keeps everything still.  And it's actually not too uncomfortable.  It's a bit difficult to fasten all 11 hooks in the front but once it's on it doesn't need adjusted and it doesn't slip move or creep.  Perfect!
