K-Pump uses enhanced ABS plastic to make a tough reliable pump that is favored by many guides and outfitters. K-Pumps are designed for use by one person with no hose to slip out. The nozzle with adapters fits all common whitewater valves or your air mattress. The K-40 is 4″ x 24″ and is the “little brother” of the K-400. Comes with it’s own carrying bag and has an unlimited 2-year warranty.
