Water Soluble fish oils that totally dissolve into the water column and travel faster and further than regular fish oil, and are easily picked up by a fish's olfactory receptors (the ability to pick up smells and scent in the water). Plus they are UV enhanced and loaded with amino acids to trigger strikes. One sniff and you'll realize how much more intense and easy to smell these new water soluble fish oils are. They are perfect for injecting into baits, or spray directly onto marabou jigs, glow bugs or chunks of sponge. They won't matt down the finest hair or feathers.
