As a new runner I quickly learned that doubling up on cheap Champion Sports Bras was not going to be enough to keep "the girls" comfortable or prevent giving other trail enthusiasts a show as we all bounced along together. After doing some research I picked up 2 Shock Absorber Extreme Support Sports Bras and 2 Moving Comfort Maia Sports Bras. The Shock Absorber is a comfortable bra with a traditional sporty look. I am a 40 D in a regular bra and bought the same size for the sports bra. While running there is some bounce, but it's not an embarrassing amount and the support is still excellent. I have been running in these a few times a week for 7 or 8 weeks and they have still held up. I would buy this product again.
