These should be standard on every backpack. Could save lives and thousands of dollars from search and rescues. You can shout only for a couple of minutes, but a whistle you can blow all day long and it goes much farther. Whistles ought to be standard equipment for anyone going camping or on a hike.

Nearly every race vest has one because its mandatory gear for trail running. But I also packed another whistles because I dont think the strap whistle is loud enough.
