The vest is like a big wearable hug that provides steady proprioceptive input (body awareness) with deep pressure and balanced weight. The effect is so gentle, calming and reassuring, kids even ask to wear it. Lightning-fast to put on, take off and adjust by adding or removing weight. For kids and adults on the autism spectrum and those with hyperactivity or sensory processing disorder. Use it any time you need extra focus or to satisfy the wiggles!
