Short Term Use Only... Beware [SEP] I thought shower caps were made to resist bacteria growth. Not true for this one. I was excited when I got these because they were really cute, double-lined and comfortable. But beware - they will start smelling and getting all mildewy within the first week or so. Very disappointed it didn't last longer than that. They also don't dry fast. It's probably the wrong material used for the outside. Never had that experience with a shower cap. Will not buy this brand ever again.
