Constructed of pre-folded sheets of a honeycomb-structured corrugated polypropylene, the HYPAR fold-up kayak is built to stand up to at least 20,000 folding cycles without leaking. That’s a lot of boating! It’s a one-person craft with a unique stern design—wide & flat, giving the boat a stable, efficient shape for cutting across the water with ease & then folds up easily to fit in the trunk of your car.
