I am absolutely amazed how comfortable this bra is. I was leary about it at first (wondering if it would give enough support, if the band would cause irritation like all of my other bras). I ordered a large, but I think I need to size up. Even though it's technically too small, it is still comfortable for me to wear (the cups are a little small for coverage). Despite this, I'm still wearing this bra every day. And it's breathable! I sweat a lot. Boob sweat causes so much irritation for me. Since wearing this bra, I haven't felt swampy or had any redness! I'm about to order some more. Give this a try. It really is a great bra.
