>>1714485I have this one which was REI branded back when I got it about 6 years ago. While searching for it I saw that they have the same Vargo one in the OP for $10.95. I noticed it is "pealess" though, I'd prefer my whistle have that rattle. I also have the one built into the Osprey pack strap, and another on my Bear Grylls Ultimate Pro Survival Knife (the most based knife ever made, name says it all).
