Slim Rescue Howler

The Slim Rescue Howler™ weighs only a few grams but it packs a big punch - namely, a 100dB signal that is audible from over a mile away. The pea-less design means this whistle works in all conditions and will never jam or freeze.

• Be Heard: 100dB whistle signal is audible over one mile.
• Fail-Safe: Pea-less design works in all conditions - won't freeze or stick to lips when cold.
• Take it Everywhere: Ultra-portable design weighs only a few grams and fits in any pocket - or attach it to a zipper pull.
