The term NONSWIMMER, PERHAPS can be solved by the five-letter word WADER. A WADER is a type of footwear used for activities such as fishing, hunting, or walking in shallow water. It is designed to protect the wearer's feet and legs from wetness and cold temperatures. Waders are typically made of waterproof material such as rubber or neoprene and are often insulated to keep the wearer warm. They are usually worn with boots or shoes and are an essential piece of equipment for anyone who spends time in or near water.
