Is this a good half pad?

My thoroughbred mare has a sore on her withers that is healing but bothers her when I ride. I have been borrowing my friends fleeceworks FXK half pad and I wanted to get my own but its a little expensive. Will this one do the same thing? a href="http://www.horseloverz.com/HDR-Fleece-Wither-Pad---White---Full-pr-290160.html" rel="nofollow"http://www.horseloverz.com/HDR-Fleece-Wi…/a
