Y-Knot - Great halters, good prices and you can choose the type of rope, number of knots, placement (if you use under bridles) as well as custom sizing for hard to fit horses. I ordered mine not long after I moved here and I think she had just started. Still have those first halters. Wash well and have worn well.
Some horse people change their horse, they change their tack and discipline, they change their instructor; they never change themselves.
