I use them all the time. I don’t need them for periods anymore, but they’re fine under leggings with a longish top. They’re great for bike riding as extra padding is always welcome. Haven’t noticed any problems with thrush and just wash them with the regular wash. If I was using them for periods, I think I’d keep a salt water bucket to soak them in after use before washing. They could sit in that for a couple of days before the next wash. Napisan wouldn’t do the elastic any good, but salt water is fine and good for getting blood out. Drying them adequately is more of a problem. I like to get them out on the line for a while at least, then into the dryer.
