Its sloped back end and swim-up step allows the rider to easily re-enter the kayak from the water. With scupper holes, multiple footrest positions, and great stability, the Wave?is perfect for kids recreational kayaking. products are made out of high-density polyethylene (HDPE) which is regarded as one of the easiest plastic polymers to recycle. Not only is HDPE easy to recycle, but when manufacturing our products, we regrind and reuse 99.5% of all plastic brought into the facilities. The plastic that is not used is sold responsibly to companies who use it for other applications. It does not end up in the landfill.
