Don’t put ice-cold metal in your horse’s mouth! Our bit warmers contain no harsh chemicals. Because rice inserts dry out after repeated use, we use 100% natural flaxseed. The polar-fleece outer cover provides insulation from the cold allowing the heat to penetrate through to the bit. You have a choice between two types of closure: Lycra ties or Velcro. Either one will hold your bit warmer in place, leaving your hands free to groom and saddle your horse. Also, it will conform to most bit sizes and shapes. You can coordinate with your barn colors or show off your personal style by choosing one of hundreds of color combinations. Customize your bit warmer with an embroidered name or monogram. Makes a great gift! and made in the USA.
