I've been using various forms of bra bags for fifteen years. My bras are expensive and hard to find, I don't like ruining them in the washing machine and it is a pain to hand wash them, thus bra bags are my thing. My preferred type of bra bag had become so cheaply made that they would typically only last three washes: at a cost of $5 a piece I might as well by new bras instead. In the last seven years I've had real difficulty finding quality bra bags for a reasonable price and I went through many types and many brands without much luck, so I was quite skeptical to try another. Thankfully, I have been pleasantly surprised by the quality of these bags. They work as promised, don't fall apart and don't come open in the washer (I hang dry my bras).I can get up to three of my DD bras in them but I prefer to put just two in there so I'm not overloading the bra bag. The bag is constructed of two different layers of mesh, a fine inner layer and a more open outer weave. The bag itself is more sturdy and heavy than most of the bra bags I have ever owned. Unlike the round bags, these bags are big enough to easily handle my large cup sized bras. I had to stuff my bras into the circular type bags, perhaps that's why they keep falling apart.PROS:Large sizeSturdy constructionDouble layer of meshZipper pocket (tuck the pull tab of zipper in this to keep it from opening)CONS:Traps fuzz in it, your bras have little pieces of fuzz on them
