incomplete set tight band single layer [SEP] i only received not the pack of i ordered i realized it after i would already opened and wore a hat overnight amazon is trying to get a price adjustment for me the hats are single layer with the rougher texture on the inside i wore it inside out so that the silkier smoother side was against my hair my hair is very much frizz prone the band is wide but tight i found myself tugging at it trying to stretch it out this set would not work for overnight oil hydration treatments because of the single layering oils will leak through and general discomfort caused by the tightness and my excessive fussing with the band
