Chin and occipital support - Firm anterior and posterior panels support the chin and occiput, limiting flexion, extension, and lateral motion.
Ventilation and procedural access - Strategically placed ventilation openings and an enlarged tracheal cut-out allow airflow and access for tracheostomy or suction.
Padding and comfort - Internal foam or padded liners reduce pressure, increase comfort, and help prevent skin breakdown.
Durable, lightweight materials - Constructed from rigid plastic shells, often CT/MRI-compatible, designed for long-term wear without being overly bulky.
Universal sizing - Many models are one-size-fits-most, covering pediatric to large adult neck sizes while saving storage space.
