No More Cold Bits! Now you can warm up your bit before riding instead of putting it under your arm to warm it up. The Bitten is used to warm your horse's bit before riding. Simply insert a single use or reusable "hand warmer" into the 2 inner mesh pockets. After the bit is warm, the Bitten can be worn around your neck (with a provided strap) and tucked inside your coat to keep you warm while riding!
