These towel caps are not it for me. Maybe because I’m just used to microfiber or thicker hair towels but these seemed thin and cheaply made. They don’t appear like they will hold up well through multiple washes. Because they’re so thin they just get wet without drying - if that makes sense. 
I gave three stars because they are comfy despite the quality, and they cutely designed with the visible label and the two buttons which is a nice feature
