Designed by the BIO Orthopaedics team in the late 1990s, it is based on the Kyphosis D.D.B., but in a minimal version. The pad is centered on the hump. It is made on a polypropylene mold with internal lining at the pressure points made from Plastazot foam material. The processing of the mold includes corrections of the kyphotic angle and lumbar lordosis. It buckles behind with straps.
Its weight and volume, in combination with the anterior buckling, makes it not acceptable for adolescents.
