Weatherproof bib and braces are designed to protect workers from the elements when working outdoors. They are made from waterproof and windproof materials to keep the wearer dry and warm in wet and cold conditions. Bib and braces are typically worn over regular work clothes and have adjustable straps for a comfortable and secure fit. They are commonly used in industries such as construction, agriculture, and forestry, where workers are exposed to harsh weather conditions.
