Waders denotes a waterproof boot 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. Waders are generally distinguished from counterpart waterproof boots by shaft height; the hip boot extending to the thigh and the Wellington boot to the knee. For the sake of emphasis, therefore, waders are sometimes defined by the extent of their coverage as thigh waders, chest waders or full-body waders. As a drysuit variant, full-body waders come with leaktight cuffs or gloves fitted to the sleeves and with a leaktight collar or hood fitted to the neck, enabling the wearer to remain dry when standing or walking in deeper water. Waders are available with boots attached or can have attached stocking feet (usually made of the wader material), to wear inside boots, or inside swimfins in the case of float tube fishing.
