Review (4/5): It's a simple shower cap.
It's a regular, plain shower cap. Works well for me. All my hair fits inside. No lining just so you know. Not giving 5 stars because I haven't had it very long. Waiting to see how long the elastic holds out. I love these for traveling because they work better than the ones you can get at a hotel and if you leave it behind, not a big deal because they are so inexpensive.
