Harkla’s weighted compression vest for kids with sensory issues combines the sensory input tool with a wearable by applying pressure to sensitive areas of the body. Simply place the vest over your child's clothing, and watch your little one return to feeling grounded and in control. The compression weighted vest for kids is made out of soft neoprene and is built to last. Unlike other brands, Harkla has built-in ventilation using mesh to make sure your child stays cool while receiving the sensory integration therapy benefits. MATERIALS: Soft Neoprene, Mesh, Velcro
