I have this one http://www.mothersboutique.com/llhiimpuspnu.html It's a La Leche nursing sports bra. I love it. Means I don't have to change bras if I need to nurse during a workout.
Judy, who owns A Mother's Boutique is a friend of mine. She's in Wexford PA, so if you are anywhere close you can go see her for a custom fitting.
