The JoViPak Chin Strap – Standard addresses edema of the neck, mandible, and the anterior/lateral aspects of the face (partially covers the ears). The open neck seam accommodates your choice of padding. The Jovi Universal Pad is designed to work with the chin strap – standard. The foam chips in the Universal Pad help to break up lymphatic fluid and move it out. Velcro straps at the neck and top of head are adjustable.
