SP (Shock Pack) lanyards are comprised of tear webbing which is woven in a manner that allows the webbing to tear when it has a load applied to it. This tearing absorbs a significant amount of downward force under load, reducing injury. This tear webbing is folded and shrink-wrapped into a compact 1 x 2 x 6 in (2.5 x 5 x 15 cm) pack that is sewn into the lanyard next to the body connector.
