Introducing the Kelly Kettle Whistle specifically designed for the Small Trekker model Kelly Kettle. This whistle is made of metal and is inserted into a soft green rubber, which not only provides comfort but also adds to its visual appeal. The color green signifies “Go,” making it easy to spot and grab during your trek. This whistle is compatible with most of our older model kettles and comes with a clip and split-ring for easy attachment. Please note that this whistle is not compatible with the large Base Camp or Scout models and does not come with a chain. Upgrade your Kelly Kettle Trekker model with this essential whistle for added safety and convenience on your next adventure.
