You never know when you might need a whistle which is why Strapworks offers a selection of whistle buckles in different sizes and colors. The buckles feature a built-in whistle that's available whenever you may need it. Whistles are a great way to grab attention and signal that you need help, but most people don't typically carry a whistle. These buckles aim to solve that problem, combining potentially life-saving whistles with an item most people use every day.
