Combat boot Combat boots are military boots designed to be worn by soldiers during combat or combat training, as opposed to during parades and other ceremonial duties. Modern combat boots are designed to provide a combination of grip, ankle stability, and foot protection suitable for a rugged environment. They are traditionally made of hardened and sometimes waterproofed leather. Today, many combat boots incorporate technologies originating in civilian hiking boots, such as Gore-Tex nylon side panels, which improve ventilation and comfort. They are also often specialized for certain climates and conditions, such as jungle boots, desert boots, and cold weather boots as well as specific uses, such as tanker boots and jump boots.
Dust mask A dust mask is a flexible pad held over the nose and mouth by elastic or rubber straps to protect against dusts encountered during construction or cleaning activities, such as dusts from drywall, brick, wood, fiberglass, silica (from ceramic or glass production), or sweeping. A dust mask can also be worn to protect against allergens. A dust mask is worn in the same fashion as a paint mask or surgical mask, but it is dangerous to confuse the three because they each protect against specific airborne dangers. Using the wrong mask for a job can present a significant and possibly deadly danger as many dust masks with widely varied levels of protection may look similar, and even masks that do not protect against dust at all, such as paint masks and surgical masks. Misfitting masks are also a danger as they allow material to bypass the mask entirely. A correct fit may not be as critical in masks that are intended to protect against splattering liquids or mists. Dust masks are manufactured to protect against only certain dangers, and do not protect against chemicals such as vapors and mists. For this reason, it is dangerous to confuse dust masks with paint masks.
