Flat cross over straps on most bitless bridles DO NOT
release easily. They can jam in the ring and be very dangerous.
Been there , did that with my mare. Straps jammed and
she went up to get away from the pressure. The cross over straps need to be
round. Round does not stick.
The Original Spirit Bridle invented years ago by Allan
Buck. He has round cross over straps so that when you release the rein it
releases the pressure.
