Screaming Banshee Buckle
This 1" side release buckle is a great thing to add to all of your packs and your kid's packs. Always have a signal whistle at hand and easy to get to on your gear. Dual double back ends mean no sewing to attach the buckles on your sternum strap. Super loud! I have one on all of my packs. Make sure the kids know how and when to use a signal whistle.
