Weighted vests are vests or jackets which are made heavier by adding small weights, which can either be stitched into the fabric or put into specially designed pockets.
Some people believe that specially weighted items, such as blankets or vests, can help autistic children cope better with a wide range of problems, such as poor motor skills, hyperactivity and sleeplessness.
They believe that the pressure of the weights helps to calm autistic children by changing how they process sensory information and by allowing them to better feel their movements and understand where their bodies are in space.
