A double-tube aluminum whistle that's loud and carries well, on a keychain so it's always with you.

It's simple and light, and it's a good one to clip on a kid's backpack before a hike so they can call out if they get separated from the group.

Pairs well with the Paracord Keychain, or the Trail Starter Kit.
