How you dress for canoeing depends on what sort of canoeing you’re doing. If it’s a casual canoeing experience with low likelihood of whitewater splashing you, then wearing clothing that is comfortable and right for the air temperature is more important than water-proofing. Wear sandals or shoes that are fine to get wet in case you do get wet. If it’s a canoe ride with fast moving water or where you ride the canoe upstream, having a life jacket, swimsuit, and waterproof shoes is a necessity.
