These shower caps are so cute. Aside from the visual aesthetics, however, they are super efficient at protecting your hair so that it stays dry in between washes. The elastic band fits snug but not so much so that it is uncomfortable or causes a headache. The cap itself is dual layered with a silky satin like fabric on the outside, lined with a waterproof barrier on the inside. I have even considered turning one inside out where the silk part outta on the inside to use as a sleeping cap to help maintain my style a little longer in between washes as well. The set came with 4 caps total. Two were a solid color and two were a polka dot design.
