Your sporting goods store may well have something that will fit your needs. Look for a bag for short skis or snowboards. There was one that used two molded plastic parts that telescoped one into the other for fitting different length skis or snowboards, and it was very durable and protective. There is a larger one that works with golf clubs. The baggage handlers are accustomed to working with this kind of bag. I also put antennas in mine for luggage transport.
