The single barrel they designed it to be as small and light as they could get it but still loud as possible. For slightly more weight, the double barrel adds more volume.\nNote: 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 caribiners will NOT fit through.\nCAUTION: Note on DB levels. All emergency whistles over 70db can cause damage to your ears. Whistles over 110 can do instant and sometimes unrepairable damage. Even though these are ultralight whistles, they can still do serious injury. Please use with caution when needed. These are not toy whistles.\n_______________________________________________Specs\nSingle barrel whistle: \n\nDimensions: 0.45\"W x 2.0\"L x 0.35\"H | 1cm x 5cm x 1cm\n\n\nWeight: 0.12oz | 3.6g\n\nDouble barrel whistle:\n\nDimensions: 0.84\"W x 2.0\"L x 0.35\"H | 2cm x 5cm x 1cm\n\nWeight: 0.24oz | 6.8g\n\nMaterials: PLA (Polylactic acid)\n\n\nDetails:  PLA (Polylactic acid) is a high-strength, thermoplastic polymer derived from renewable, organic sources such as corn starch and sugar cane.
