All Weather Safety Whistle Wind Storm Black 2 5/8″ with Keyring

This high-impact thermoplastic whistle delivers sound loud enough to cut through crowds, howling wind, and competing noise—making it effective for signaling in chaotic or outdoor conditions. At 2 5/8″ overall, it’s compact enough to attach to a keyring for easy carry. The design performs reliably in wet or dry environments and will produce sound above, on, or below the water, so it functions whether you’re on land, in rough conditions, or in the water. Its adoption by the U.S. military reflects proven reliability for emergency signaling. Suitable for campers, hikers, boaters, hunters, scuba divers, and sporting event officials who need a dependable audible alert.
