The Airstream Telescopic Blowpipe is easily adjusted to the desired height to ensure your posture is correct. This is a great product for younger players who are still growing as they can be easily be lengthened as the player grows. Having the correct length of blowpipe is very important. This blowpipe has all of the same characteristics as the regular Airstream Blowpipe, like a wide bore with built-in Little Mac Valve and oval mouthpiece for increased air flow. The Airstream Telescopic Blowpipe will fit any set of pipes.
