13 Fishing Sneak Superior Soft Plastics are 10 times tougher and last longer than the competition. Designed for ice fishing, these baits are infused with 13 Fishing's "Donkey Sauce," a proprietary formulation of amino acids and proteins that stimulate feeding and aggression in predatory game fish. The pyramidal appendages transfer vibrations and the HD ultra-fine features create life-like movement that triggers more strikes.
