The one I received is made with two parallel rolls around the neck that expand completely and evenly when soaked in water.  It is attractive, and will keep you cooler for awhile on a very hot day, at least until it starts to dry out and eventually lose the cooling effect.  It helps to keep it in the refrigerator and take to location in a cooler box before use, but don't freeze-  it will just stick together and not work well!
