You already have a lot of straps and buckles to do, undo and redo before you get on. Make your saddle strap a permanent addition to every saddle you ride in & have one less strap to fasten. The lanyard and saddle strap must be fitted correctly in order for the air jacket system to work correctly.
We strongly recommend that you get one saddle strap per saddle and you leave each securely attached at all times. Please see the instruction manual supplied with the jacket for help in attaching your saddle strap.
