If your bird's FlightSuit™ is slightly too big, you can utilize our "String Method" to help adjust the fit. Simply take a ribbon or string to loop underneath the elastic straps on the back - once the FlightSuit is on your bird. Pull and tie the two ends into a small bow in the center of his back. This will bring the fit of the FlightSuit™ closer to your bird and should eliminate any tripping issues. You should find that you will no longer need to use this adjustment as it fully grows into it's FlightSuit™.
