Limited quantities available and no backorders on the item - Kurgo has discontined this SKU. 8 years were spent building the Impact Harness. That's 8 years of trying, failing, learning, planning, engineering and crash-testing car harnesses, and it's all gone into the Impact Harness (this one is the medium, black & charcoal color). It uses a single piece of tubular webbing with reinforced bar tacking. The result? A veritable monument to safety and comfort, built to the standards the Federal Motor Vehicle Safety Standards created for child restraint systems.
