Work wear is made up of useful apparel and accessories that can be worn in a variety of settings. In extreme cold, chemical warmers are worn inside gloves and shoes to keep hands and feet warm. Cooling vests keep workers cool in hot conditions. When working in freezing climates, electronically heated work wear contains battery-powered heating elements that warm the torso. Jackets, coats, caps, and other everyday work gear are included in this category. Scrubs are a type of clothing that is ideal for lab work and medical settings. Rainwear is comprised of waterproof material to keep workers dry when working in wet or dirty environments. Snakebite gaiters protect the lower leg and ankle from snake bites by preventing penetration.
