We recommend to purchase the AE2011 pump to inflate the product. The AdvancedFrameConvertible is a 15-foot kayak that can be paddled solo or tandem, offering the best of both worlds. Its open deck design allows for easy entry and exit, and optional single or double decks quickly convert it into a closed deck kayak. The rigid bow and stern rib-frame design combine with interchangeable decks and seating positions for maximum versatility. *Pump not included
