it can sometimes be better, but more expensive, to buy the parts seperatley.. a headpiece that would fit a full size horse and a cob, then buy check pieces .... measure the horses face to get the right length... then get a browband again after you have measured, then get a noseband.
different manufactures have all different sizes from each other,,, also uk and usa sizes are totally different.
much like trying to buy clothes it does drive me mad they are never the same!!
i am fed up with the speed and the greed of the world around me but i have not found nor can i offer a cure
