I'm a 34B and I found this bra did a pretty good job of support while I'm running. Still not quite as good as a typical hardcore running bra, but the best natural fiber sports bra I've found. I wish it came in other colors than black! Be aware that a slight odor from the bamboo fabric persists even after one laundering, though it does fade...
I was so excited when I saw this sports bra. I am always trying to find a sports bra that supports me and that is soft and comfortable. I was disappointed with this bra however. It is very soft and comfortable but it doesn't give me any support. Right now I am a 36C, usually a 34B but I am nursing right now so my breast are bigger and heavier and this bra just doesn't give me any support. I ordered two of these bras and I have decided to keep them to do my pilates and other low impact activities..
This is my FAVORITE sport bra! It is of VERY high quality, thick, absorbant, supportive and SO comfortable, and I love that it is made with bamboo. It is incredible...
