No day out on your paddle board or kayak is possible without paddles. SUP paddles only have a paddle on one end and a small handle to grip on the other. Kayak paddles are double sided. The majority of paddles are adjustable, so you can create a perfect fit for your height and skill level. Most SUP paddles should be 6-8" taller than you. A kayaker should determine paddle length based off their height and the width of their kayak.
