The New Snood Hijab Caps Ideal hijab cap for sisters with long hair.  Ladies do not have to worry about their hair falling out from under their hijab or looking bulky. These hijab caps are similar to the rhinestone accent hijab caps but with an extension (snood) in the back and an elastic band at the back of the neck to gently hold their hair in place and hold the cap on the head. Snood Hijab caps are made of polyester with a touch of spandex for comfort and easy wear.
