Traditionally, a pure wool blanket called a Witney Blanket, was used as under blanket for the stabled horse, with a roller placed over the stable rug and under blanket to hold it in place. Modern under blankets however, resemble lightweight stable rugs and are more commonly known as under rugs. These tend to have special fixings to attach the under rug or rug liner to the outer rug, so there is no need to use a roller. Different under blankets are designed to be worn with stable rugs, turnout rugs.
