All of our younger/Beaver Scouts are required to wear a neck lanyard with whistle when we're hiking or camping. New break-away lanyards are a little out of our budget so we found a simple solution: We solved the problem by either using a length of rope, or a regular layard that has been cut, and tying a slip knot in the end. They are secure enough to hold the "not a toy!" whistle but will come loose if tugged.
