Emergency Survival Whistle

A whistle carries much further than a voice and costs you no energy. This one packs four more things into the same body.

• Loud pealess whistle that still works wet
• Flint striker for lighting a fire
• Liquid-filled compass in the cap
• Watertight compartment for matches
• Signal mirror and an orange lanyard so it hangs where you can reach it

Clip one to each bag and one to the children's coats.
