Wicking ability of wool pads

Several years ago I decided to make my own saddle pads entirely out of wool or wool blends (or a
layer of cotton over one or more layers of wool). Almost all commercial English saddle pads have a layer of foam between the cloth interior and exterior, which does not wick away sweat and heat as well as wool. As you can see by the photos, Blessi sweated quite a bit during his workout (need to renew his hunter trim) but his back was dry and not overheated. Let's hear it for those lovely sheep!
