I have heard many opinions at our barn. If you have a Wool Pad, (ie Todd Slone or Impact Gel Wool Pad) do you have to have a wool blanket underneath the Wool Pad? Most everyone puts a wool blanket underneath the wool pad?? (blanket, wool pad, saddle) I don't understand why, when the Pad is Wool. Is it because the wool blanket aid in absorbing the sweat? Or because they want to keep the actual Wool Pad from being the sweat absorber? I thought the Wool Pads could go directly on the horses back and you could just use a blanket if preferred as posted earlier for a colorful look.
