There are others on the list who have much more Icelandic experience than I have, but our Tosca uses a small horse sized halter and bridle. Yrsa's head is more cob-sized.
It was funny, our friends who own Lina told me to take horse sized halters when we went to pick them up. I couldn't believe that was true, but gathered an assortment of sizes from the tack room and found that they were right - small horse size. Nancy
