Super happy with this bra after wearing it for at least 3 longer runs. As with any bra, don't forget to Glide the ribcage before running.

The only other high impact bras that actually work for me feel like armor or have the classic, two strap style (which make my traps ache and don't really work with my tank tops).  This bra keeps the (C-cup) everything in place for my runs. The lower neckline provides a little breathability.  Fit is true to size, and the bra comfortable enough for everyday use.
