Loud Whistle

Hand them out to protect your loved ones & your local community!

Tiny enough to forget it's there until you need it — then loud enough that everyone within earshot knows exactly where you are. This ultra-light whistle packs a serious 131+ dB punch into a design that weighs practically nothing, making it dead simple to bring with you anywhere you go.

Why it's good
 

Absurdly loud: 131+ dB means it cuts through noisy environments and long distances when it matters most.
Weighs next to nothing: At ~1 gram, there's zero reason not to carry one everywhere.
Always-on-you safety: Small enough to carry anywhere and never notice it.
Be prepared: Blow and it works. Every time.
