I've grown tired of bras with underwires and stumbled upon these types of bras by accident. I purchased one for travel primarily to save space and leave my pricey bras at home. It was the most comfortable bra I've worn since my "training" bra at 12.  My concern was support as I wear a 38DD but I hard noticed I had it on and I wasn't racing to take it off when I returned after a long evening.  I have since purchased 3 more and as the description says "Cozy" it is not a substitute for a sports bra; with that being said I will be purchasing extras for yoga/Zumba class since I don't do hardcore work outs.
