I take a really good care of my long thick hair and round brush and blow dry it to perfection, so i need a great shower cap. I take long hot showers and I'm 5'3 so the water directly hits the top of my head. This shower cap is 100% waterproof! most i have used are nylon water resistant and my hair ends up wet. This one holds all my hair is soft terry lines is tight by not too tight, I have a lot of hair. I wish it came in other colors. pricey for a shower cap but it has last 6 months so far, i had to buy another one because i left it at hotel.
