The Horseware Vari-Layer Liner is new to the Horseware Liner System, adding more warmth with less weight for all your liner compatible blankets. A simple system, Horseware Liners give your blankets superior insulation properties without the need for two blankets. The liner attaches by Velcro loop to the neck area of the outer blanket and clips onto the back corners to prevent the liner from slipping. Liner can be easily washed in a domestic washing machine.
