I've been using this brand of Fox 40 for seven years, my first being one I nabbed after my first college lifeguarding gig. Can confirm that they're pretty indestructible, work when soaking wet or partially submerged, and will last you years, if you don't chew off the mouthpiece. It's been a staple in my hiking/backpacking bags for years. I cannot confirm how far the sound will travel while out on trail, but you can easily hear three whistle blasts when you're in a crowd of 500+ 4th of July partiers.
