For sizing most children will wear the same size as they would in jeans. View JettProof Sizing Chart JettProof leggings assist children that wriggle and provide sensory input to calm their sensory system. JettProof leggings help create body awareness plus provide proprioceptive feedback (information received from muscles and tendons, concerning body movement and position), to assist children to stay calm, focus and learn. They have been designed for comfort with no internal stitching (for a seamless feel), no centre seam and no tags. JettProof is manufactured from a high quality, breathable, moisture-wicking, special sensory fabric which is durable and keeps the wearer cool, dry and comfortable all year round. If your measurement is between two sizes, you are best choosing the smaller size.
