Halters are made of different types of materials, each comes with its own advantages and disadvantages. Typically, horse halter is available in three different materials, leather, nylon, and rope.  But leather is the most commonly used because of its durability and practicality. On the other hand, nylon is very popular as nylon halters are cheap and strong (virtually unbreakable). However, for many years, rope halters have been the no: 1 choice for expert riders because they are designed in a way only to be handled by experienced horse trainers or handlers.
