The OTC 0316 KidsLine knee support is excellent for use in athletic activities or as a general use post-injury support. KidsLine is OTC's family of Pediatric and Youth sized products. They are cut and assembled to follow the same anatomically correct profile as our popular adult versions, but are "right sized" to fit a smaller frame. Pediatric sizes will generally fit children from 2 to 7 years of age. Youth sizes will fit kids from 8 to 12 years old.
