Everrich EVZ-0005 Deep Pressure Sensory Vests - X-Large This vest is designed to be pulled snug against the child body, providing proprioceptive deep pressure feedback and stability over the chest and waist. The vest is made of two separate pieces, front and back, that attach with wide strips of hook-and-loop fasteners. That allows the therapist to adjust and vary the dimensions to meet the needs of different children. It is made of Airprene, a material that has tiny perforations throughout the fabric to reduce overheating. The vest is secured with a hook-and-loop back. For accurate fit, measure circumference around widest point of chest for width. Measure length from shoulder to waist. Durable and machine washable. Colors vary. Size: X-Large. Dimensions: 48 W x 26 L.
