I purchased this bra after undergoing breast reduction surgery.  I needed a bra that was 1) supportive, 2) no underwire, 3) not a pull over.  This bra fits the bill on all three needs.  It is very comfortable and I am able to sleep in it.  I have also begun to walk and use my elliptical and I have been able to wear this bra for both of these exercises with no discomfort.  It has a 3 hook closure in the back and the shoulder straps are also adjustable so it's pretty easy to use for working out or sleeping.  I ordered 2 initially but was so pleased that I ordered 2 more.  If I had to pick a downside - it may be visible under regular clothes (v-neck, scoop neck).  I wear baggy scrubs with a v-neck top and I have seen it peeking out.  On the plus side, it had a very smooth top with nice stitching and if you don't know it's a bra it looks like a cami.
