Not fit for all [SEP] So, I work in nursing and decided that I would give these a try since I like to keep my hair covered at work. I have long hair so purchased these since they are said for long hair. Well, let's start with the buttons. The placement of the buttons is dumb.  Directly over the ears. So, even though I didn't intend to use them at work, since I use a K95, they pushed down on top of my ears and caused a lot of pain. I ended up removing the buttons immediately. Useless. Next, let's talk about the fact that there is NO elasticity in the cap at all. I'm sure if you have an extra large crowned head, they might fit better. But these caps slide right off of my hair. Which made for an awkward situation. The cap slid off, the straps of my mask started to slide then. Eventually I had to just remove the cap. I tried all 3 caps and found that none of them stayed on my head. I tried to hand wash them with the hopes they would shrink some, but that didn't work either. In the end, these caps are not fit for all heads. I will not repurchase, and I will be more careful when purchasing similar items in the future. Stay safe everyone!
