Here's a link to an old thread about sports bras for bootcamp.. http://www.uscg.org/Forum/aft/13901.aspx
Another benefit of the Moving Comfort fiona is that is has the hook and eye closure in the back. (Have you ever tried pulling on a max support sports bra when your skin is still damp after a shower? I felt like I was fighting with my bra after showers every night)
I brought only one fiona (regretted that decision) and the rest were another recommended buy: walmart's Danskin Now high impact bras, just doubled up. The larges can fit a smaller D.
