Aspen® Cervical Collars Pads wick moisture while shell distributes and transfers head weight to shoulders and upper thorax. Fit upright or supine patients. Front and back airflow openings. Adjustable Occipital Support Strap™. Aspen TX includes thoracic extension. Both models include a breathable pad set (front and back) and extra set of replacement pads. Aspen® Cervical Collars were designed to optimize support and comfort, two key components for better patient outcomes. The structure of the collar was engineered to provide substantial motion restriction without producing painful pressure points that can lead to skin breakdown or poor patient compliance. For the ultimate in comfort, all contact surfaces of the collar are cushioned with cotton-lined, breathable foam padding.
