Our exclusive 8-layer weighted blanket features a soft, grippy top layer that uses no glue to increase durability and an ultra-breathable base layer that contains millions of micro-glass beads designed to provide comfort and relaxation throughout the night. All layers are lined with high quality polyester. The combination of these layers ensures optimal temperature control , while the super soft second layer prevents the beads from penetrating the blanket itself. The beads are non-toxic, hypoallergenic, latex-free and phthalate-free.
