The Original Stretchy, Comfy Neoprene Vest Provides Weight and Compression Our founder and occupational therapist Aviva couldn’t find a weighted compression vest for kids, so she designed her own. This vest was our first Fun and Function product and it’s still one of our top sellers. It’s like a reassuring hug, perfect for helping to calm down, focus or cope with sensory overload. The steady proprioceptive input and compression around the trunk are especially soothing for those with sensory challenges. With stretchy neoprene for a snug, comfy fit and the subtle black design, older kids even ask to wear it.
