These wraps and blankets provide proprioceptive feedback and stability. Designed to be used with weight sets and other sensory items. The wraps are for swaddling, while the blankets are wider and intended for resting. Small channels run diagonally along the length of both items for the weight strips. Hook-and-loop fasteners at the end of the channels secures the weights in place. Larger channels allow you to place other sensory items safely inside. Sensory items can also be attached directly to the fabric using hook-and-loop fasteners. Made of nylon fabric with a polyester foam core. Soft, comfortable, flame retardant, and machine washable (remove weights before washing).
