I put this bra on and felt like I wasn't even wearing a bra...it is seriously that comfortable. Riding with this bra on was completely wonderful. I felt no weight in my chest and no tension in my shoulders from the straps. I didn't even really feel the straps at all. We're given so many reasons why we have certain pains but I've never had anyone suggest wearing the wrong bra while cycling was causing me to have some pain around my neck and shoulders. After wearing this just once I can tell that my bra was the reason to the problems and this bra was perfect the solution. I'm a 32 B and the small fits perfectly for me. I just wish I had lots more money so I could buy more.
