LUKE: Those would be called waders.
Waders, waterproof boots or overalls extending from the foot to the thigh, the chest or the neck. They are traditionally made from vulcanised rubber, but available in more modern PVC, neoprene and Gore-Tex variants. The first waders were made in 1838 by a company called Hodgman, in Framingham, Massachusetts.
