When kayaking, you can expect to get wet—especially if you’re using a sit-on-top kayak. So wear something that you wouldn’t mind getting damp and dirty. (Odds are, you’ll also work up a sweat while kayaking. So keep that in mind, too). If it’s hot out, consider wearing a swimsuit, a T-shirt, shorts, and waterproof shoes. (Look for shoes that will stay fastened to your feet, even under pressure. You might end up walking through the water, so looser-fitting shoes, like flip-flops, may fall off.) If it’s cooler out, wear what you might wear on a cold hike. Just remember that you might get wet from head-to-toe, so make sure you’d be comfortable getting your shoes completely wet.
