Harness with a variable inside space, depending on what protection is applied, whether a fiberglass back plate with polyethylene foam (120 mm) or a back plate made of polyethylene foam (160 mm). Side protectors can also be installed on the harness. The down part of the harness is made of PVC. For better aerodynamics the strap system is hidden under the neoprene inserts.
One more feature: speed-system on the outside.
