I am 5'5" tall, 175 pounds , and wear a D cup bra. The Under Armour Women's UA Seamless Advantage Sports Bra is perfect for lounging around or recumbent bike. Any low impact activity. I would not advise Running or Jogging, but if you are looking for a sweat wicking sports bra for walking this one has you covered.  I plan to wear it on a trip to a tropic climate.
