The TRS arm restraints are designed to keep the drivers arms and hands inside the car in the event of an accident or rollover. They will not hinder movement and are adjustable to to provide freedom of movement. The arm restraints are covered in the same fire-retardant materials we use on the shells of our racing suits - not cheaper nylon sold by some other manufacturers.

These will go around your arms and then be secured to the lap belts of your harness.
