Simpson D3 Restraints
The D3 provides the ease and convenience of a sewn in harness without the harness being sewn to the lap belt. The unique design eliminates two links but still allows the shoulder harness to be joined closely together at the buckle, emulating a true latch and link racing system.
In independent testing, nylon belts have been shown to stretch during resistance and loose strength when exposed to rain, sweat or any liquid. Polyester belts are superior to nylon at absorbing energy during a crash test. In other words, they stretch less, keeping you away from the steering wheel and tightly in your seat. Affect of exposure to liquids is also minimal. Polyester webbings resistance to the elements is critical in off-road racing where conditions are often extreme and less controlled.
