Elastic not strong enough to hold heavy layers
I have a pretty big head and long hair in a bun.  The cap was plenty big but the elastic can't hold the stiff plastic and 2nd wet cloth layer on my forehead, it falls back down to my eyebrows.  I ordered the polka dot plastic ones instead.  They barely fit, ponytail instead of bun, but the elastic is tight all around.
