Whistles Ultralight & Loud by Hilltop Packs

Ultralight And Ultra-Loud
Hilltop Packs made these emergency whistles to be ultra-loud for alerting others when needed. The single barrel version is as small and light as you can get while still being loud. The double barrel adds a tad more weight but also packs a louder sound into its small size.
The hole is big enough to put a cord through for use as a necklace or an extra carrying handle. Any cord with a 2.2mm diameter or smaller will fit (including 550 paracord). The single-barrel version will also fit most keyrings. However, most carabiners will NOT fit through.
