A chin strap to keep jaw firmly closed, with 5 "D" rings, two on each side and one Additional pressure from three leather straps around the outside of the padded hood creates a more confining feeling. Straps are positioned around the padded eyes, over the mouth and from the point of the chin around the back of the head. Extra keepers prevent straps from moving out of position. Five "D" rings fixed to the chin strap can be used to totally immobilize the head.
This hood has a 1/4" grommet hole over the mouth and mouth strap that allow for breathing. Both of these holes can be changed to a 1/2" grommet if you want a slightly bigger opening, just indicate in the comments field when ordering.
