Cut through the noise in any conditions with this pealess finger grip whistle from Crown Sporting Goods. Traditional pea whistles only work when their cork pea is bone dry, but any competitor knows that the weather won't always allow for that. Pealess whistles use specially-engineered chambers to produce a shrill with just a burst of air (which you provide, of course). Thanks to this, pealess whistles are impervious to rain and frost and can't be overblown. The shrill only gets louder the harder you blow. And for our more mobile users who can't be bothered with the dangle of a lanyard, these pealess whistles are perched on top of a 2-inch adjusting finger grip. Slide it right on your hand and get moving! Or, if you need both hands free, each whistle also includes a soft plastic mouth grip so you can comfortably carry a whistle in your mouth. We've really thought of everything.
