JettProof calming compression shorts are a popular choice to wear under clothing to assist children that wriggle, to provide sensory input and calm their sensory system, help create body awareness plus provide proprioceptive feedback (information received from muscles and tendons, concerning body movement and position). JettProof shorts assist children to stay calm, focus and learn and have been designed for comfort with no internal stitching (for a seamless feel), no centre seam and no tags. For sizing most children will wear the same size as they would in regular shorts and jeans.
