Being resistant to temperature changes not only ensures that the housing will remain a constant temperature, even in cold and wet conditions, but will not experience the expansion and contraction common in metal chassis that can cause the optical elements to move out of alignment over time and hinder the binocular's ability to achieve sharp focus. The chassis is covered in a black rubber armoring that helps to protect it from drops and impacts and provides a slip-resistant grip.
