I recently bought a halter from Sunset Halters and have to say it's exactly what I wanted. I remember using a friend's Parelli halter and noticing how "soft" it was (cheap ones you get from Tractor Supply are stiff and poorly made). This one had a nice material that reminded me of the Parelli halter.. and it was inexpensive! I've been looking for something similar to the Parelli halter and I finally found it (material-wise). I definitely recommend them.
