2-ply 3/4" nylon web. Brass-plated die-cast rings and buckles. Comes with 2 crown pieces, letting it grow with your horse from foal up to weanling in size.
I had a hard time fitting a halter to my foals at a week old. The regular suckling halters hung off of them. The grow with me halters are fitted to the head and I dont have to worry that the foal will get a hoof through the halter if left on.
