I bought this, as well as 3 other types. I use this one as my back up when I have washed my favorite brand (WingsLove). I have been using all of them this summer and have been fine with sweating and working long days painting in a school with no A/C. These are comfortable. I often forget I have them on. I am small, so I ordered the A cup. The cups are a little deeper than my favorite brand, which is why I have this rated as a 4 and not a 5. I prefer the other brand's less deep cups.
